a40e6fb67a Change check_refname_format() to reject unnormalized refnames
Since much of the infrastructure does not work correctly with
unnormalized refnames, change check_refname_format() to reject them.

Similarly, change "git check-ref-format" to reject unnormalized
refnames by default.  But add an option --normalize, which causes "git
check-ref-format" to normalize the refname before checking its format,
and print the normalized refname.  This is exactly the behavior of the
old --print option, which is retained but deprecated.

7e9d2fe960 Do not allow ".lock" at the end of any refname component
Allowing any refname component to end with ".lock" is looking for
trouble; for example,

    $ git br foo.lock/bar
    $ git br foo
    fatal: Unable to create '[...]/.git/refs/heads/foo.lock': File exists.

Therefore, do not allow any refname component to end with ".lock".

e4ed6105ec git check-ref-format: add options --allow-onelevel and --refspec-pattern
Also add tests of the new options.  (Actually, one big reason to add
the new options is to make it easy to test check_ref_format(), though
the options should also be useful to other scripts.)

Interpret the result of check_ref_format() based on which types of
refnames are allowed.  However, because check_ref_format() can only
return a single value, one test case is still broken.  Specifically,
the case "git check-ref-format --onelevel '*'" incorrectly succeeds
because check_ref_format() returns CHECK_REF_FORMAT_ONELEVEL for this
refname even though the refname is also CHECK_REF_FORMAT_WILDCARD.
The type of check that leads to this failure is used elsewhere in
"real" code and could lead to bugs; it will be fixed over the next few
commits.

a0a7e9e511 check-ref-format doc: de-emphasize the implementation detail of a ref
It is an unimportant implementation detail that branches and tags are
stored somewhere under $GIT_DIR/refs directory. What is more important
is that branches live in refs/heads and tags live in refs/tags hierarchy
in the ref namespace.

f028cdae66 Documentation: link to gitrevisions rather than git-rev-parse
Currently, whenever we need documentation for revisions and ranges, we
link to the git-rev-parse man page, i.e. a plumbing man page, which has
this along with the documentation of all rev-parse modes.

Link to the new gitrevisions man page instead in all cases except
- when the actual git-rev-parse command is referred to or
- in very technical context (git-send-pack).

cc1b8d8bc6 docs: don't talk about $GIT_DIR/refs/ everywhere
It is misleading to say that we pull refs from $GIT_DIR/refs/*, because we
may also consult the packed refs mechanism. These days we tend to treat
the "refs hierarchy" as more of an abstract namespace that happens to be
represented as $GIT_DIR/refs. At best, this is a minor inaccuracy, but at
worst it can confuse users who then look in $GIT_DIR/refs and find that it
is missing some of the refs they expected to see.

This patch drops most uses of "$GIT_DIR/refs/*", changing them into just
"refs/*", under the assumption that users can handle the concept of an
abstract refs namespace. There are a few things to note:

  - most cases just dropped the $GIT_DIR/ portion. But for cases where
    that left _just_ the word "refs", I changed it to "refs/" to help
    indicate that it was a hierarchy.  I didn't do the same for longer
    paths (e.g., "refs/heads" remained, instead of becoming
    "refs/heads/").

  - in some cases, no change was made, as the text was explicitly about
    unpacked refs (e.g., the discussion in git-pack-refs).

  - In some cases it made sense instead to note the existence of packed
    refs (e.g., in check-ref-format and rev-parse).

0b444cdb19 Documentation: spell 'git cmd' without dash throughout
The documentation was quite inconsistent when spelling 'git cmd' if it
only refers to the program, not to some specific invocation syntax:
both 'git-cmd' and 'git cmd' spellings exist.

The current trend goes towards dashless forms, and there is precedent
in 647ac70 (git-svn.txt: stop using dash-form of commands.,
2009-07-07) to actively eliminate the dashed variants.

Replace 'git-cmd' with 'git cmd' throughout, except where git-shell,
git-cvsserver, git-upload-pack, git-receive-pack, and
git-upload-archive are concerned, because those really live in the
$PATH.

38eedc634b git check-ref-format --print
Tolerating empty path components in ref names means each ref does
not have a unique name.  This creates difficulty for porcelains
that want to see if two branches are equal.  Add a helper associating
to each ref a canonical name.

If a user asks a porcelain to create a ref "refs/heads//master",
the porcelain can run "git check-ref-format --print refs/heads//master"
and only deal with "refs/heads/master" from then on.

3e262b95c5 Don't permit ref/branch names to end with ".lock"
We already skip over loose refs under $GIT_DIR/refs if the name
ends with ".lock", so creating a branch named "foo.lock" will not
appear in the output of "git branch", "git for-each-ref", nor will
its commit be considered reachable by "git rev-list --all".

In the latter case this is especially evil, as it may cause
repository corruption when objects reachable only through such a
ref are deleted by "git prune".

It should be reasonably safe to deny use of ".lock" as a ref suffix.
In prior versions of Git such branches would be "phantom branches";
you can create it, but you can't see it in "git branch" output.

cbdffe4093 check_ref_format(): tighten refname rules
This changes the rules for refnames to forbid:

 (1) a refname that contains "@{" in it.

     Some people and foreign SCM converter may have named their branches
     as frotz@24 and we still want to keep supporting it.

     However, "git branch frotz@{24}" is a disaster.  It cannot even
     checked out because "git checkout frotz@{24}" will interpret it as
     "detach the HEAD at twenty-fourth reflog entry of the frotz branch".

 (2) a refname that ends with a dot.

     We already reject a path component that begins with a dot, primarily
     to avoid ambiguous range interpretation.  If we allowed ".B" as a
     valid ref, it is unclear if "A...B" means "in dot-B but not in A" or
     "either in A or B but not in both".

     But for this to be complete, we need also to forbid "A." to avoid "in
     B but not in A-dot".  This was not a problem in the original range
     notation, but we should have added this restriction when three-dot
     notation was introduced.

     Unlike "no dot at the beginning of any path component" rule, this
     rule does not have to be "no dot at the end of any path component",
     because you cannot abbreviate the tail end away, similar to you can
     say "dot-B" to mean "refs/heads/dot-B".

For these reasons, it is not likely people created branches with these
names on purpose, but we have allowed such names to be used for quite some
time, and it is possible that people created such branches by mistake or
by accident.

To help people with branches with such unfortunate names to recover,
we still allow "branch -d 'bad.'" to delete such branches, and also allow
"branch -m bad. good" to rename them.

b1889c36d8 Documentation: be consistent about "git-" versus "git "
Since the git-* commands are not installed in $(bindir), using
"git-command <parameters>" in examples in the documentation is
not a good idea. On the other hand, it is nice to be able to
refer to each command using one hyphenated word. (There is no
escaping it, anyway: man page names cannot have spaces in them.)

This patch retains the dash in naming an operation, command,
program, process, or action. Complete command lines that can
be entered at a shell (i.e., without options omitted) are
made to use the dashless form.

The changes consist only of replacing some spaces with hyphens
and vice versa. After a "s/ /-/g", the unpatched and patched
versions are identical.

This default regex now matches explicit values, and unfortunately in this
case gitlink was being matched by just 'link', causing the wrong inline
macro template to be applied. By renaming the macro, we can avoid being
matched by the wrong regex.
