[PATCH 1/2] 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. This ensures there's
at the least a simple example that illustrates what could be done
using the hook just by enabling it.

 I have made the second patch depend on the first one to avoid
 conflicts that may occur. Further, it was meaningful to join
 the two patches as they would go together (or) not at all.
