"git check-ignore" did not work when the given path is explicitly
marked as not ignored with a negative entry in the .gitignore file.
* en/check-ignore:
check-ignore: fix documentation and implementation to match
check-ignore has two different modes, and neither of these modes has an
implementation that matches the documentation. These modes differ in
whether they just print paths or whether they also print the final
pattern matched by the path. The fix is different for both modes, so
I'll discuss both separately.
=== First (default) mode ===
The first mode is documented as:
For each pathname given via the command-line or from a file via
--stdin, check whether the file is excluded by .gitignore (or other
input files to the exclude mechanism) and output the path if it is
excluded.
However, it fails to do this because it did not account for negated
patterns. Commands other than check-ignore verify exclusion rules via
calling
... -> treat_one_path() -> is_excluded() -> last_matching_pattern()
while check-ignore has a call path of the form:
... -> check_ignore() -> last_matching_pattern()
The fact that the latter does not include the call to is_excluded()
means that it is susceptible to to messing up negated patterns (since
that is the only significant thing is_excluded() adds over
last_matching_pattern()). Unfortunately, we can't make it just call
is_excluded(), because the same codepath is used by the verbose mode
which needs to know the matched pattern in question. This brings us
to...
=== Second (verbose) mode ===
The second mode, known as verbose mode, references the first in the
documentation and says:
Also output details about the matching pattern (if any) for each
given pathname. For precedence rules within and between exclude
sources, see gitignore(5).
The "Also" means it will print patterns that match the exclude rules as
noted for the first mode, and also print which pattern matches. Unless
more information is printed than just pathname and pattern (which is not
done), this definition is somewhat ill-defined and perhaps even
self-contradictory for negated patterns: A path which matches a negated
exclude pattern is NOT excluded and thus shouldn't be printed by the
former logic, while it certainly does match one of the explicit patterns
and thus should be printed by the latter logic.
=== Resolution ==
Since the second mode exists to find out which pattern matches given
paths, and showing the user a pattern that begins with a '!' is
sufficient for them to figure out whether the pattern is excluded, the
existing behavior is desirable -- we just need to update the
documentation to match the implementation (i.e. it is about printing
which pattern is matched by paths, not about showing which paths are
excluded).
For the first or default mode, users just want to know whether a pattern
is excluded. As such, the existing documentation is desirable; change
the implementation to match the documented behavior.
Finally, also adjust a few tests in t0008 that were caught up by this
discrepancy in how negated paths were handled.

The standard for command documentation synopses appears to be:
[...] means optional
<...> means replaceable
[<...>] means both optional and replaceable
So fix a number of doc pages that use incorrect variations of the
above.

There are a handful of incorrect "linkgit:<page>[<section>]"
instances in our documentation set.
* Some have an extra colon after "linkgit:"; fix them by removing
the extra colon;
* Some refer to a page outside the Git suite, namely curl(1); fix
them by using the `curl(1)` that already appears on the same page
for the same purpose of referring the readers to its manual page.
* Some spell the name of the page incorrectly, e.g. "rev-list" when
they mean "git-rev-list"; fix them.
* Some list the manual section incorrectly; fix them to make sure
they match what is at the top of the target of the link.

By default git check-ignore shows only the filenames that will be
ignored, not the pattern that causes their exclusion. Instead of moving
the partial exclude pattern precendence information to the -v option
where it belongs, link to gitignore(5) which describes this more
thoroughly.

The synopsys text and the usage string of subcommands that read list
of things from the standard input are often shown like this:
git gostak [--distim] < <list-of-doshes>
This is problematic in a number of ways:
* The way to use these commands is more often to feed them the
output from another command, not feed them from a file.
* Manual pages outside Git, commands that operate on the data read
from the standard input, e.g "sort", "grep", "sed", etc., are not
described with such a "< redirection-from-file" in their synopsys
text. Our doing so introduces inconsistency.
* We do not insist on where the output should go, by saying
git gostak [--distim] < <list-of-doshes> > <output>
* As it is our convention to enclose placeholders inside <braket>,
the redirection operator followed by a placeholder filename
becomes very hard to read, both in the documentation and in the
help text.
Let's clean them all up, after making sure that the documentation
clearly describes the modes that take information from the standard
input and what kind of things are expected on the input.

By default, check-ignore does not list tracked files at all since
they are not subject to ignore patterns.
Make this clearer in the man page.

check-ignore currently shows how .gitignore rules would treat untracked
paths. Tracked paths do not generate useful output. This prevents
debugging of why a path became tracked unexpectedly unless that path is
first removed from the index with `git rm --cached <path>`.
The option --no-index tells the command to bypass the check for the
path being in the index and hence allows tracked paths to be checked
too.
Whilst this behaviour deviates from the characteristics of `git add` and
`git status` its use case is unlikely to cause any user confusion.
Test scripts are augmented to check this option against the standard
ignores to ensure correct behaviour.

check-ignore doc: fix broken link to ls-files page
test: spell 'ls-files --delete' option correctly in test descriptions
check-attr and check-ignore have the potential to deadlock callers
which do not read back the output in real-time. For example, if a
caller writes N paths out and then reads N lines back in, it risks
becoming blocked on write() to check-*, and check-* is blocked on
write back to the caller. Somebody has to buffer; the pipe buffers
provide some leeway, but they are limited.

If `-n` or `--non-matching` are specified, non-matching pathnames will
also be output, in which case all fields in each output record except
for <pathname> will be empty. This can be useful when running
check-ignore as a background process, so that files can be
incrementally streamed to STDIN, and for each of these files, STDOUT
will indicate whether that file matched a pattern or not. (Without
this option, it would be impossible to tell whether the absence of
output for a given file meant that it didn't match any pattern, or
that the result simply hadn't been flushed to STDOUT yet.)
