[PATCH/RFC] hooks: replace irrelevant hook sample

[Kaartic Sivaraam <kaarticsivaraam91196@gmail.com>]

The pre-commit-msg hook sample has an example that comments
the "Conflicts:" part of the merge commmit. It isn't relevant
anymore as it's done by default since 261f315b ("merge & sequencer:
turn "Conflicts:" hint into a comment", 2014-08-28).

Add an alternative example that replaces it to ensure there's
atleast one example that could be used just by enabling the hook.

 This patch assumes that a previous patch that touched the commit
 template [1] has been appled. Else it could remove the information
 about the branch from the comments.
