Martin von Zweigbergk 7791a1d9b9 Documentation: use [verse] for SYNOPSIS sections
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.

git-patch-id(1)
===============
NAME
----
git-patch-id - Compute unique ID for a patch
SYNOPSIS
--------
[verse]
'git patch-id' < <patch>
DESCRIPTION
-----------
A "patch ID" is nothing but a SHA1 of the diff associated with a patch, with
whitespace and line numbers ignored. As such, it's "reasonably stable", but at
the same time also reasonably unique, i.e., two patches that have the same "patch
ID" are almost guaranteed to be the same thing.
IOW, you can use this thing to look for likely duplicate commits.
When dealing with 'git diff-tree' output, it takes advantage of
the fact that the patch is prefixed with the object name of the
commit, and outputs two 40-byte hexadecimal strings. The first
string is the patch ID, and the second string is the commit ID.
This can be used to make a mapping from patch ID to commit ID.
OPTIONS
-------
<patch>::
The diff to create the ID of.
