[PATCH v2 0/4] doc: include git rev-list description in git log doc

This series moves the nice explanation in the 'Description' section of the git rev-list man page to a separate file and includes this file in the git log man page.

This goal is to make readers more aware that they can write e.g.

git log branch1 branch2 branch3 branch4 --not master

to see commits on each of branch1-4, that are not on master, since this is not immediately obvious (at least to me) in the git log man page.

Note that I made several commits for ease of reviewing, I'll squash some if this would be preferred.

Changes since v1: took a completely different approach following the comments received from Junio and Taylor.

     -    doc: log takes multiple revision ranges
     +    git-log.txt: add links to 'rev-list' and 'diff' docs
      
     -    `git log` accepts multiple revision ranges, but makes no mention of that
     -    in its documentation. Currently readers have to go to the `git
     -    rev-list` documentation to discover this useful feature.
     -
     -    Mention it and adjust the synopsys in the doc and in the short
     -    help for `git log`.
     -
     -    Also add links to the documentation for `git rev-list` and `git diff`
     +    Add links to the documentation for `git rev-list` and `git diff`
          instead of simply mentioning them, to make it easier for readers to reach
          these documentation pages. Let's link to `git diff` as this is the
          porcelain command, and the rest of the family (`diff-index`, `diff-tree` and
