Subject: [PATCH] gitk: Fix missing commits when using -S or -G

From: Stefan Dotterweich <[email-masked]>
Date: Fri, 6 May 2016 13:56:21 +0200

When -S or -G is used as a filter option, the resulting commit list
rarely contains all matching commits. Only a certain number of commits
are displayed and the rest are missing.

"git log --boundary -S" does not return as many boundary commits as you
might expect. gitk makes up for this in closevargs() by adding missing
parent (boundary) commits. However, it does not change $numcommits,
which limits how many commits are shown. In the end, some commits at the
end of the commit list are simply not shown.

Change $numcommits whenever a missing parent is added.
