[PATCH 1/6] doc: log, gitk: move '-L' description to 'line-range-options.txt'

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

From: Philippe Blain <levraiphilippeblain@gmail.com>

The description of the '-L' option for `git log` and `gitk` is the
same, but is repeated in both 'git-log.txt' and 'gitk.txt'.

Remove the duplication by creating a new file, 'line-range-options.txt',
and include it in both files.
