bug in logging

[Igor Schein <igor@txc.com>]

Hi,

when I run gp with -test, and log the session in a file, the output
doesn't get logged into the log file, only the input.  The man pages
says that -test is for benches only, but here's an obvious case where
a user needs it:  I want to run something and send the output to
another person thru email.

Thanks

Igor
