[PATCH 1/3] rebase -i: highlight problems with core.commentchar

[Junio C Hamano <gitster@pobox.com>]

From: Johannes Schindelin <johannes.schindelin@gmx.de>

The interactive rebase does not currently play well with
core.commentchar. Let's add some tests to highlight those problems
that will be fixed in the remainder of the series.
