Perhaps I was cutting and pasting sections of my script file.  
Things weren't working well and bash's expansion of ! inside double
quotes wasn't adding to my general computer enjoyment.

But since we are talking about reading the bash man page, please let
me enter exhibit A into evidence. ;-)

       Enclosing  characters  in double quotes preserves the lit-
       eral value of all characters within the quotes,  with  the
       exception  of  $, `, and \.  The characters $ and ` retain
       their special meaning within double quotes.  The backslash
       retains  its  special meaning only when followed by one of
       the following characters: $, `, ",  \,  or  <newline>.   A
       double quote may be quoted within double quotes by preced-
       ing it with a backslash.

No where do I see mention of ! being expanded in quotes.  Since other
shells don't do this, I would think the path of least surprise is to
change bash to not do it either.
