Subject: script: don't flush input when starting script
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e8c7a57b4fafb16a4cbf535c8e07066b20ed9551;p=util-linux

script: don't flush input when starting script

script currently flushed the input buffer when starting up.  This undocumented
behaviour prevents typeahead when starting up (e.g. as part of .profile).
Rather retain queued input. Don't discard queued output either.
