From: Anders Melchiorsen <mail@xxxxxxxxxxxxxxxx>
We explicitly let the user know that an empty commit message
will abort the commit. At the same time, we take the
opportunity to reword the template text a bit to keep it
more compact.
This patch also makes the "fatal: empty commit message?"
warning a bit less scary, since this is now a "feature"
instead of an error. However, we retain the non-zero exit
status to indicate to callers that nothing was committed.
[jk: I compacted the text and expanded the commit message
from Anders' original patch]
