[StGit PATCH 0/6] Two bugfixes

This series fixes one rather benign bug (4/6) and one that caused patches to become empty, which is rather worse (6/6). (The patch contents could still be recovered via the patch log or reflog, but it's still a major inconvenience.)

Both bugs were discovered by Erik Sandberg.

These patches are also available in the kha/safe branch.
