As always, you can never cover all cases during tests :)
While these things surely make sense, I will not add them right now. As
you said, we can do that later.
Taking about spaces:
I think spaces before the "-" are not supported before/after the rewrite
(I remember that strto.* does not skip over them). Spaces after the
space should be covered by strto* automatically (strto.* skips over
leading spaces).
Thanks!
