But re commit 44915d6953076, 

HG>          tty_num=$(echo "$tty" | grep -oE '[0-9]+$')

Is grep -o available everwhere startx(1) runs?

The posix page, grep.1p, does not mention -o.

It looks like each of the BSDs have adopted it, but only midstream
(eg, its documented in OpenBSD 5.0, but not in 4.9).
