[PATCH v3 6/6] git-log.txt: include rev-list-description.txt

["Philippe Blain via GitGitGadget" <gitgitgadget@gmail.com>]

From: Philippe Blain <levraiphilippeblain@gmail.com>

The `git log` synopsis mentions `<revision range>`, and the description
of this option links to gitrevisions(7), but a nice explanation of
how a revision range can be constructed from individual commits,
optionnally prefixed with `^`, also exists in `rev-list-description.txt`.

Include this description in the man page for `git log`.

Add Asciidoc 'ifdef's to `rev-list-description.txt` so that either `git
rev-list` or `git log` appears in the respective man pages.

 short-hand for "^'<commit1>' '<commit2>'". For example, either of
 the following may be used interchangeably:

 Another special notation is "'<commit1>'...'<commit2>'" which is useful
 for merges.  The resulting set of commits is the symmetric difference
 between the two operands.  The following two commands are equivalent:

 -----------------------------------------------------------------------
 $ git rev-list A B --not $(git merge-base --all A B)
