I usually cheat like heck on this one and use 'screen'.  I require use 
of 'screen' for some stuff at $WORK so that if the user is kicked off 
the VPN or whatever, they can recover.  But as an added bonus, you can 
get this kind of logging.  Except--come to think of it, I'm not 100% you 
still don't get the control characters (and I can't check at the 
moment)...  So YMMV.

SCREEN='/usr/bin/screen'
[...|
$SCREEN -X logfile $LogDirPrefix/file.log \
  && $SCREEN -X log on
# code goes here
$SCREEN -X logfile 1  # Set logfile buffer to 1 sec. (default's 10)
$SLEEP 3              # Wait 3 seconds, to avoid truncation
$SCREEN -X log off    # Turn off the log


The other way to cheat is to use the terminal's scroll-back buffer 
and/or logging feature.  That works great for docs but not so well for 
logging scripts from cron or whatever.  Though the OP question did sound 
kind of interactive...

HTH,
JP

"Microsoft Tax" = the additional hardware & yearly fees for the add-on
software required to protect Windows from its own poorly designed and
implemented self, while the overhead incidentally flattens Moore's Law.
