It looks like this is a bug in the way path-restrictions are
applied for diffs. The toplevel "pidgin" dir (of the current
workspace) was named "gtk" in rev d33475..., but the renamed
dir doesn't get included in the path-restriction, causing
the error. I'll look at fixing that - maybe parent
directories need to be included in restrictions?

A workaround would be to run
"mtn diff -r d33475 ..", and then manually look for the
changes for winprefs.c

Thanks for the bug report.
