From: Johannes Schindelin <johannes.schinde...@gmx.de>
This command does not do a whole lot so far, apart from showing a usage
that is oddly similar to that of `git tbdiff`. And for a good reason:
the next commits will turn `range-branch` into a full-blown replacement
for `tbdiff`.
At this point, we ignore tbdiff's color options, as they will all be
implemented later using diff_options.
Since f318d739159 (generate-cmds.sh: export all commands to
command-list.h, 2018-05-10), every new command *requires* a man page to
build right away, so let's also add a blank man page, too.
