For $initial_reply_to, I think "empty" means "I do not want to make
this message reply to anything", so I think it is OK to either give
a default "", or extendign valid_re to also catch an empty string.
In either case, the prompt message may want to clarify what happens
when you give an empty input (e.g. "leave this empty to start a new
thread", or something).

If you let $to to go empty with the first hunk of your patch, where
does the mail eventually go?  Does anybody later in the code decide
to add some recipient?  If there is a reason why an empty input is a
valid here, I think there is a stronger need (that is, stronger than
the above ase for $initial_reply_to) to explain when the user wants
to leave this empty.
