[PATCH] gitk: Heed the lines of context in merge commits.

[Johannes Sixt <j.sixt@viscovery.net>]

From: Johannes Sixt <johannes.sixt@telecom.at>

There is an edit box where the number of context lines can be chosen.
But it was only used when regular diffs were displayed, not for
merge commits. Fix this.
