It seems that various other open source Unixen dropped that between 29
and 2 years ago, but not illumos.  I guess no one ever had IO::Pty
installed on an older OpenBSD or NetBSD machine or we'd have seen this
problem there too, but as of a few years ago they behave like Linux
and FreeBSD: no tab expansion.
