Details:
Hi.
I've found out that ':' for stdin in an exec pattern doesn't
work. The reason is that if '!' is used for stdin, then the
w_pty fd is just duped to the sub process, so that the p_pty
is bypassed. But with ':' there is a relay mechanism via the
p_pty. In order to match the behaviour of the bypassed pty,
the pty must be set to raw mode, which is what the attached
patch does.
Without the attached patch, if the relayed data does not contain
the '\n's, the sub-process will simply receive nothing at all, because
the pty is then line-buffered.
Does the patch look good?
