	How lame!  It's a '!' in a quoted string.  Another example
 of posix braindeath -- how long before people realize that the
thing branded 'posix' now isn't the real posix that was started
to *describe* behaviors, not prescribe or proscribe behaviors.
They just bought the name -- like PacBell swallowed SW Bell and
then bought the AT&T name (not the labs... just the name).  So that
AT&T today is really the old PacBell in new shoes...

	It's like its really tweaky watching a first run anime from
Japan (in japanese) with a Universal logo on it... and words that it is
an NBC company.  (Who is now owned by Comcast).

	Oh well when I role my own, I think I usually leave
histexpand out of it.  Having to remember line numbers seems
ridiculous... and I can search by hitting ESC /string (in vi
mode anyway).
