gitk: Fix diffing committed -> staged (typo in diffcmd)

jlehmann · paulusmack · commit 90a779254176 · 2009-11-03T22:28:34.000+11:00
When highlighting a commit, using the context menu over the staged changes
and then selecting "Diff this -&gt; selected" the diff was empty.  The same
happened when highlighting the staged changes and using "Diff selected -&gt;
this" over a commit.  The reason was a copy/paste error in [diffcmd].
This fixes it.
