AFAICS this is limitation due to way ')spool' is currently implemented.

When I need to record input and output I normally either use terminal
cut and paste (for small things) or 'script' program (for larger
volume). Both ways have a drawback: recorded info contains control
characters sent by 'clef' or 'rlwrap', but ATM I found them good
enough.
Concerning ')spool', I do not think that we should keep current
implementation. OTOH we should clean out our input-output machinery
and with cleaned up implementation correct implementation of ')spool'
should be easy.
