Subject: gitk: Fix some bugs with path limiting in the diff display
X-Git-Url: https://privyetmir.co.uk/gitweb.cgi?a=commitdiff_plain;h=bd8f677e1c8349b9128490e2a21e0f573d0bea1d;p=gitk

gitk: Fix some bugs with path limiting in the diff display

First, we weren't putting "--" between the ids and the paths in the
git diff-tree/diff-index/diff-files command, so if there was a tag
and a file with the same name, we could get an ambiguity in the
command.  This puts the "--" in to make it clear that the paths are
paths.

Secondly, this implements the path limiting for merge diffs as well
as the normal 2-way diffs.
