This allows a natural user-interface when looking for any change in the
code, not just regression. For example:
git bisect start --term-old fast --term-new slow
git bisect fast
git bisect slow
...
There were several proposed user-interfaces for this feature. This patch
implements it as options to 'git bisect start' for the following reasons:
* By construction, the terms will be valid for one and only one
bisection.
* Unlike positional arguments, using named options avoid having to
remember an order.
* We can combine user-defined terms and passing old/new commits as
argument to "git bisect start".
* The implementation is relatively simple.

When not looking for a regression during a bisect but for a fix or a
change in another given property, it can be confusing to use 'good'
and 'bad'.
This patch introduce `git bisect new` and `git bisect old` as an
alternative to 'bad' and good': the commits which have a certain
property must be marked as `new` and the ones which do not as `old`.
The output will be the first commit after the change in the property.
During a new/old bisect session you cannot use bad/good commands and
vice-versa.
Some commands are still not available for old/new:
* git rev-list --bisect does not treat the revs/bisect/new and
revs/bisect/old-SHA1 files.

This enhances the support for bisecting history in bare repositories.
The "git bisect" command no longer needs to be run inside a repository
with a working tree; it defaults to --no-checkout when run in a bare
repository.

The SYNOPSIS sections of most commands that span several lines already
use [verse] to retain line breaks. Most commands that don't span
several lines seem not to use [verse]. In the HTML output, [verse]
does not only preserve line breaks, but also makes the section
indented, which causes a slight inconsistency between commands that
use [verse] and those that don't. Use [verse] in all SYNOPSIS sections
for consistency.
Also remove the blank lines from git-fetch.txt and git-rebase.txt to
align with the other man pages. In the case of git-rebase.txt, which
already uses [verse], the blank line makes the [verse] not apply to
the last line, so removing the blank line also makes the formatting
within the document more consistent.
While at it, add single quotes to 'git cvsimport' for consistency with
other commands.

The point of these sections is generally to:
1. Give credit where it is due.
2. Give the reader an idea of where to ask questions or
file bug reports.
But they don't do a good job of either case. For (1), they
are out of date and incomplete. A much more accurate answer
can be gotten through shortlog or blame. For (2), the
correct contact point is generally git@vger, and even if you
wanted to cc the contact point, the out-of-date and
incomplete fields mean you're likely sending to somebody
useless.
So let's drop the fields entirely from all manpages except
git(1) itself. We already point people to the mailing list
for bug reports there, and we can update the Authors section
to give credit to the major contributors and point to
shortlog and blame for more information.
Each page has a "This is part of git" footer, so people can
follow that to the main git manpage.
This patch adds an asciidoc version of the "Fighting regressions with
git bisect" article that the author wrote for the Linux-Kongress
2009 (http://www.linux-kongress.org/2009).
This paper might be interesting to people who want to learn as much as
possible about "git bisect" from a single document.
The slides of the related presentation are available at:
http://www.linux-kongress.org/2009/slides/fighting_regressions_with_git_bisect_christian_couder.pdf
But the Linux Kongress people will not publish this paper online because
they print the papers on their UpTimes magazine
(http://www.lob.de/isbn/978-3-86541-358-1). But they don't take away the
rights of the author (which is very nice), so I have the right to publish
it.

‘git bisect reset’ accepts an optional argument specifying a branch to
check out after cleaning up the bisection state. This lets you
specify an arbitrary commit.
In particular, this provides a way to clean the bisection state
without moving HEAD: ‘git bisect reset HEAD’. This may be useful if
you are not interested in the state before you began a bisect,
especially if checking out the old commit would be expensive and
invalidate most of your compiled tree.
Clarify the ‘git bisect reset’ documentation to explain this optional
argument, which was previously mentioned only in the usage message.

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.

If a branch named "bisect" or "new-bisect" already was created in the
repo by other means than git bisect, doing a git bisect used to override
the branch without a warning. Now if the branch "bisect" or
"new-bisect" already exists, and it was not created by git bisect itself,
git bisect start fails with an appropriate error message. Additionally,
if checking out a new bisect state fails due to a merge problem, git
bisect cleans up the temporary branch "new-bisect".

This teaches "git bisect visualize" to be more useful in non-windowed
environments.
(1) When no option is given, and $DISPLAY is set, it continues to
spawn gitk as before;
(2) When no option is given, and $DISPLAY is unset, "git log" is run
to show the range of commits between the bad one and the good ones;
(3) If only "-flag" options are given, "git log <options>" is run.
E.g. "git bisect visualize --stat"
(4) Otherwise, all of the given options are taken as the initial part
of the command line and the commit range expression is given to
that command. E.g. "git bisect visualize tig" will run "tig"
history viewer to show between the bad one and the good ones.
As "visualize" is a bit too long to type, we also give it a shorter
synonym "view".
