Good catch Bob! Funny thing is that when I wrote this at the shell
prompt to test it I actually did stick a character in (I use 'z'
instead of an underscore, some old habit). I took it out so I would
not have to explain why it was there. In retrospect I should've, no
point in spreading bad habits :-(
