The answer no doubt lies in the fact that the window size is obtained
via an ioctl:  `TIOCGSIZE'.  Presumably Sun's tset is performing
this on its standard output, and inside backquotes this is tied to
a pipe rather than the terminal.  If you have source, you may be
able to fix tset by making the ioctl happen on 0 or 2 (stdin or
stderr).

Sun changed their termcap routines to know about the `li#' and
`co#' entries, and to return the appropriate values based on the
window size, if available.  Thus programs like `more' work without
modification.
