It is a common mistake to put positional arguments before flags when
invoking git-rev-list. Order the positional arguments last.

This patch skips git-rev-list invocations which include the --not flag,
since the ordering of flags and positional arguments affects the
behavior. This patch also skips invocations of git-rev-list that occur
in command substitution in which the exit code is discarded, since
fixing those properly will require a more involved cleanup.

I screwed up by putting the positional argument *after* the
redirection. Sorry for the mix-up. This is interestingly syntactically
valid, though bad stylistically. Here is an inter-diff:

Thanks for being careful.  Except for a rather idiomatic 

	echo >&2 message ...

which has redirection at the beginning to emphasize that the output
goes to the standard error stream, I do agree with your "stylistic"
choice of keeping the redirection at the end.
