I'll install PuTTY, try toybox hg head, and play with them later, see
if I can reproduce that segfault.  I use the last released tarball of
toybox, an old Ubuntu, and a bunch of other terminal proggies.  I did
not know that PuTTY had been ported to Unix.

But as I mentioned, not interested in a bug hunt right now.  That will
be more appropriate when it's less of a "sandbox for testing the ideas"
and more of a "good enough to bother using".  Always good to have other
terminals for testing though.
