ce4a706388 revision arguments: ..B means HEAD..B, just like A.. means A..HEAD
For consistency reasons, we should probably allow that to be written as
just "..branch", the same way we can write "branch.." to mean "everything
in HEAD but not in "branch".

384e99a4a9 rev-list --boundary
With the new --boundary flag, the output from rev-list includes
the UNINTERESING commits at the boundary, which are usually not
shown.  Their object names are prefixed with '-'.

For example, with this graph:

              C side
             /
	A---B---D master

You would get something like this:

	$ git rev-list --boundary --header --parents side..master
	D B
        tree D^{tree}
        parent B
        ... log message for commit D here ...
        \0-B A
        tree B^{tree}
        parent A
        ... log message for commit B here ...
        \0

fb18a2edf7 Fix error handling for nonexistent names
When passing in a pathname pattern without the "--" separator on the
command line, we verify that the pathnames in question exist. However,
there were two bugs in that verification:

 - git-rev-parse would only check the first pathname, and silently allow
   any invalid subsequent pathname, whether it existed or not (which
   defeats the purpose of the check, and is also inconsistent with what
   git-rev-list actually does)

 - git-rev-list (and "git log" etc) would check each filename, but if the
   check failed, it would print the error using the first one, i.e.:

	[torvalds@g5 git]$ git log Makefile bad-file
	fatal: 'Makefile': No such file or directory

   instead of saying that it's 'bad-file' that doesn't exist.

This fixes both bugs.

c348f31ab9 revision traversal: --remove-empty fix (take #2).
Marco Costalba reports that --remove-empty omits the commit that
created paths we are interested in.  try_to_simplify_commit()
logic was dropping a parent we introduced those paths against,
which I think is not what we meant.  Instead, this makes such
parent parentless.

Marco Costalba reports that --remove-empty omits the commit that
created paths we are interested in.  try_to_simplify_commit()
logic was dropping a parent we introduced those paths against,
which I think is not what we meant.  Instead, this marks such
parent uninteresting.  The traversal does not go beyond that
parent as advertised, but we still say that the current commit
changed things from that parent.

8efdc326c9 rev-lib: Make it easy to do rename tracking (take 2)
prune_fn in the rev_info structure is called in place of
try_to_simplify_commit. This makes it possible to do rename tracking
with a custom try_to_simplify_commit-like function.

This commit also introduces init_revisions which initialises the rev_info
structure with default values.

f3219fbbba try_to_simplify_commit(): do not skip inspecting tree change at boundary.
When git-rev-list (and git-log) collapsed ancestry chain to
commits that touch specified paths, we failed to inspect and
notice tree changes when we are about to hit uninteresting
parent.  This resulted in "git rev-list since.. -- file" to
always show the child commit after the lower bound, even if it
does not touch the file.  This commit fixes it.

Thanks for Catalin for reporting this.

d2c4af7373 Don't recurse into parents marked uninteresting.
revision.c:make_parents_uninteresting() is exponential with the number
of merges in the tree. That's fine -- unless some other part of git
already has pulled the whole commit tree into memory ...

ea5ed3abce get_revision(): do not dig deeper when we know we are at the end.
This resurrects the special casing for "rev-list -n 1" which
avoided reading parents unnecessarily.

64bc6e3db5 setup_revisions(): handle -n<n> and -<n> internally.
This moves the handling of max-count shorthand from the internal
implementation of "git log" to setup_revisions() so other users
of setup_revisions() can use it.

765ac8ec46 Rip out merge-order and make "git log <paths>..." work again.
Well, assuming breaking --merge-order is fine, here's a patch (on top of
the other ones) that makes

	git log <filename>

actually work, as far as I can tell.

I didn't add the logic for --before/--after flags, but that should be
pretty trivial, and is independent of this anyway.

a4a88b2bab git-rev-list libification: rev-list walking
This actually moves the "meat" of the revision walking from rev-list.c
to the new library code in revision.h. It introduces the new functions

	void prepare_revision_walk(struct rev_info *revs);
	struct commit *get_revision(struct rev_info *revs);

to prepare and then walk the revisions that we have.

ae563542bf First cut at libifying revlist generation
This really just splits things up partially, and creates the
interface to set things up by parsing the command line.

No real code changes so far, although the parsing of filenames is a bit
stricter. In particular, if there is a "--", then we do not accept any
filenames before it, and if there isn't any "--", then we check that _all_
paths listed are valid, not just the first one.

The new argument parsing automatically also gives us "--default" and
"--not" handling as in git-rev-parse.
