[Chicken-users] are additional make-input-port's argument ok to use

[F. Wittenberger]

Hi all,

me again :-(

I'm inclined to use those undocumented arguments to make-input-port (for
read-line and read-string).  However before I go ahead I'd like to know
how stable the interface is.  Or may it be even ok to make them
official?

Thanks
