Hi Mathieu,

Mathieu Othacehe <othacehe <at> gnu.org> skribis:

Yes.

I haven’t actually tested the patch but it LGTM.  One thing to check is
whether ‘terminal-window-size’ returns something sensible for the
pseudo-terminal; it could be that we need an extra ioctl so the
pseudo-terminal has the same size as the actual terminal.

Neat!

LGTM, modulo the terminal size issue mentioned above.
