Sorry for a long delay.  I tried this (and Pedro's) patch today.  They
both do the job, so one of them should IMO be committed, master and
branch.

I indeed think that the condition should be removed.  I see no need
for it: there's no reason to make any stream displayed on TUI more
than line-buffered.

Thanks.
