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.

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.

This makes the rewrite easier to validate in that revision flag
parsing and warlking part are now all in rev_info structure.

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.

Also, make it a fatal error to pass in a non-commit object. The callers
never checked, so better check here.
This simplifies merge-base further. It's now so trivial that it's almost
ridiculous.
- mark_reachable() can be more generic, marking the reachable revisions
with an arbitrary mask.
- date parsing will parse to a date of 0 rather than ULONG_MAX for the
bad old case, sorting the dates correctly.
This also drops the old-style date parsing. We just don't care
enough, since we dropped that format pretty early.
Yes, this could do with some cleanup, and a common library file.
Some day.
It's really a very generic thing: the notion of one sha1 revision
referring to another one. "fsck" uses it for all nodes, and "rev-tree"
only tracks commit-node relationships, but the code was already
the same - now we just make that explicit by moving it to a common
header file.
