problem with trailing comment in repl

[Jose A. Ortega Ruiz]

hi,

currently, when entering a sexp in the repl with a trailing comment,
there's no prompt in response (although the sexp is evaluated):

    [/home/jao]$ guile -q
    GNU Guile 1.9.15.16-9970c
    Copyright (C) 1995-2010 Free Software Foundation, Inc.

    Guile comes with ABSOLUTELY NO WARRANTY; for details type `,show w'.
    This program is free software, and you are welcome to redistribute it
    under certain conditions; type `,show c' for details.

    Enter `,help' for help.
    scheme@(guile-user)> (define a 3) ;; foo
    <- cursor stays here; no prompt


is that intended? i'm hoping it is not, because it confuses geiser, who
is waiting for a new prompt to mark the end of the transaction.

cheers,
jao
