updated for version 7.4.205 Problem: ":mksession" writes command to move to second argument while it does not exist. When it does exist the order might be wrong. Solution: Use ":argadd" for each argument instead of using ":args" with a list of names. (Nobuhiro Takasaki)

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