updated for version 7.4.052 Problem: With 'fo' set to "a2" inserting a space in the first column may cause the cursor to jump to the previous line. Solution: Handle the case when there is no comment leader properly. (Tor Perkins) Also fix that cursor is in the wrong place when spaces get replaced with a Tab.

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