[racket-dev] , en and enter! sometimes do nothing, and it's changing over releases?

I've been seeing the same behavior.  I think something got broke in
racket/enter "enter!".   I don't think it is a Geiser, XRepl issue other
then both I believe leverage the racket/enter module.  Bit of a pain in the
arse bug, nice if someone could look in to it.

Thanks,

Ray
