Ultrix 4.1 /bin/sh and /bin/sh5 $PATH trailing colon bug

[Ian! D. Allen [CGL]]

#!/bin/sh
# This fails for /bin/sh and /bin/sh5 on Ultrix 4.1 and Ultrix 3.1.
# A leading or trailing ":" in $PATH is supposed to mean the current
# directory.  The leading ":" works; the trailing ":" does not.
# A trailing double-colon works.    idallen at watcgl.waterloo.edu
