Subject: gitk: Fixed broken exception handling in diff
X-Git-Url: https://privyetmir.co.uk/gitweb.cgi?a=commitdiff_plain;h=7272131b3e49879d3a7bedacad3cdb12ae678ee8;p=gitk

gitk: Fixed broken exception handling in diff

If the tree diff command failed to start for some
random reason, treepending remained set, and thus
no more diffs were shown after that.
