While being at the topic of :sort, I noticed there seems to be a bug
with :sort, that it will try to sort, even when there would be nothing
to sort.
Using the example from Axel, and do :sort! r /foobar/
You'll notice, Vim will randomly sort your buffer. So here is a patch,
that skips sorting, if the RE doesn't match anything (this might also be
caused by an illegal pattern) and will therefore not randomly change
your buffer. So here is a patch.
Best,
Christian
