I'm pretty certain that my comment here was with respect to the ":",
which made me think "hmmm, won't : always exit successfully?". My
slightly less ignorant self of today answers "sure, but we won't always
get that far" -- the "exec" is pretty important, and it will cause the
current shell to be replaced with the hook invocation. So however the
pre-commit hook decides to exit, that'll be our exit status.

I retract my comment from back then.
