updated for version 7.3.014 Problem: Ending a line in a backslash inside an ":append" or ":insert" command in Ex mode doesn't work properly. (Ray Frush) Solution: Halve the number of backslashes, only insert a NUL after an odd number of backslashes.

#! /bin/sh
#
# which.sh -- find where an executable is located.  It's here because the
# "which" command is not supported everywhere.  Used by Makefile.
