updated for version 7.3.472 Problem: Crash when using ":redraw" in a BufEnter autocommand and switching to another tab. (??) Solution: Move triggering the the autocommands to after correcting the option values. Also check the row value to be out of bounds. (Christian Brabandt, Sergey Khorev)

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