'A...B' is a shortcut for 'A B --not $(git-merge-base --all A B)'.
This XOR-like operation is called symmetric difference in set
theory.
The symbol '...' has been chosen because it's rather similar to the
existing '..' operator and the somewhat more natural caret ('^') is
already taken.

* lt/rev-list:
setup_revisions(): handle -n<n> and -<n> internally.
git-log (internal): more options.
git-log (internal): add approxidate.
Rip out merge-order and make "git log <paths>..." work again.
Tie it all together: "git log"
Introduce trivial new pager.c helper infrastructure
git-rev-list libification: rev-list walking
Splitting rev-list into revisions lib, end of beginning.
rev-list split: minimum fixup.
First cut at libifying revlist generation

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.

In addition, also fixes a few synopses to be more consistent and a gitlink.

The fixes focuses on improving the HTML output. Most noteworthy:
- Fix the Makefile to also make various *.html files depend on
included files.
- Consistently use 'NOTE: ...' instead of '[ ... ]' for additional
info.
- Fix ending '::' for description lists in OPTION section etc.
- Fix paragraphs in description lists ending up as preformated text.
- Always use listingblocks (preformatted text wrapped in lines with -----)
for examples that span empty lines, so they are put in only one HTML
block.
- Use '1.' instead of '(1)' for numbered lists.
- Fix linking to other GIT docs.
- git-rev-list.txt: put option descriptions in an OPTION section.

The replacement was performed automatically by these commands:
perl -pi -e 's/link:(git.+)\.html\[\1\]/gitlink:$1\[1\]/g' \
README Documentation/*.txt
perl -pi -e 's/link:git\.html\[git\]/gitlink:git\[7\]/g' \
README Documentation/*.txt

An earlier commit causes a mismatch in <emphasis> and <superscript>
tags, one way of fixing it is having no more than one caret symbol per
line, which is the only solution I found in the asciidoc
documentation. Ugly, but it works.
[jc: ugly indeed but that is not Peter's fault.]

This patch tidies up the git-rev-list documentation and epoch.c, which
are in severe clash with the unwritten coding style now, and quite
unreadable.
It also fixes up compile failures with older compilers due to variable
declarations after code.
The patch mostly wraps lines before or on the 80th column, removes
plenty of superfluous empty lines and changes comments from // to /* */.

This patch linearises the GIT commit history graph into merge order
which is defined by invariants specified in Documentation/git-rev-list.txt.
The linearisation produced by this patch is superior in an objective sense
to that produced by the existing git-rev-list implementation in that
the linearisation produced is guaranteed to have the minimum number of
discontinuities, where a discontinuity is defined as an adjacent pair of
commits in the output list which are not related in a direct child-parent
relationship.
With this patch a graph like this:
a4 ---
| \ \
| b4 |
|/ | |
a3 | |
| | |
a2 | |
| | c3
| | |
| | c2
| b3 |
| | /|
| b2 |
| | c1
| | /
| b1
a1 |
| |
a0 |
| /
root
Sorts like this:
= a4
| c3
| c2
| c1
^ b4
| b3
| b2
| b1
^ a3
| a2
| a1
| a0
= root
Instead of this:
= a4
| c3
^ b4
| a3
^ c2
^ b3
^ a2
^ b2
^ c1
^ a1
^ b1
^ a0
= root
A test script, t/t6000-rev-list.sh, includes a test which demonstrates
that the linearisation produced by --merge-order has less discontinuities
than the linearisation produced by git-rev-list without the --merge-order
flag specified. To see this, do the following:
cd t
./t6000-rev-list.sh
cd trash
cat actual-default-order
cat actual-merge-order
The existing behaviour of git-rev-list is preserved, by default. To obtain
the modified behaviour, specify --merge-order or --merge-order --show-breaks
on the command line.
This version of the patch has been tested on the git repository and also on the linux-2.6
repository and has reasonable performance on both - ~50-100% slower than the original algorithm.
This version of the patch has incorporated a functional equivalent of the Linus' output limiting
algorithm into the merge-order algorithm itself. This operates per the notes associated
with Linus' commit 337cb3fb8da45f10fe9a0c3cf571600f55ead2ce.
This version has incorporated Linus' feedback regarding proposed changes to rev-list.c.
(see: [PATCH] Factor out filtering in rev-list.c)
This version has improved the way sort_first_epoch marks commits as uninteresting.
