It is understandable that a Git GUI that cannot be started looks like a
problem that needs solving. However, I am not happy with the proposed
solution.
The first reason is that even if Git GUI can now run, the error message
still reappears every time when Rescan (F5) is used and must be
dismissed each time. (The version of Git GUI that I use does a rescan on
window activation and now runs into rescan loop after the dismission; I
can't even exit Git GUI anymore.)

This is the second reason. As a first step, an attempt should be made to
fill the edit box with the unprocessed commit message.
I am unsure what next steps should be, though.
- Should we not allow to make a commit?
- Should we allow to edit the message and then permit a commit?
I can't tell, because I do not know for what purposes people use the
prepare-commit-msg hook.
Without these two points addressed, I consider it better that Git GUI
does not even start or exits.

Below this context is the same catch {file delete ...}. Since it is now
reached, the instance in the if-branch should be removed.
