If POSIX says it is allowed, we need to support it obviously.
Optionally, we could issue a warning about bad style.

If POSIX says it is not allowed or leaves it unspecified, I'd
say, that we should deprecate it in a future release. Pretty much
the same way you are handling the terminating ';' issue.
However, since it used to work and is now broken it needs to be
put back in temporarily. Personally, I feel that incompatible
changes should be announced first.
