File won't be committed if it was rejected by pre-commit

[tpwo]

There is a check that stops committing a zettel if there is no output in git diff (i.e. there were no changes between the recent version). This is good when I just enter and exit (with pyzet edit) an already committed zettel without adding a thing.

But when pre-commit rejects committing a zettel, it is already staged. So, if I enter and exit the zettel with pyzet edit it won't be committed.

I see a solution in checking for git diff --staged if git diff is empty. This should also check for this edge case. Another solution is to unstage zettel when pre-commit rejects it, but it's probably harder to implement. IDK at this point, and will decide later.
