ZSH and typeahead

ZSH and typeahead

[Andrej Borsenkow]

It is not a big deal, but I just discovered, that typeahead is lost. ZSH
sees only the first line; all others are just vanished.

Is it by design? I have a feeling, that it didn't happen before. this is
Zefram's version (including build patches).

It may be system dependent; there used to be a problem with Ultrix that
you had to read the data already present before changing the terminal
settings, else suchlike weird things would happen.  It doesn't seem
to be happening here (IRIX).

Yep. Here is patch to configure which detects it for SINIX (and
RelianUNIX). I cannot test it for all versions, but it is needed for two
of them I currently have.
