Hmmm. That's not supposed to happen!!! Hmmmm. "Conventional wisdom" says that 
the double-quotes don't protect the asterisk. However, reading the bash 
man-page we have:

"Enclosing  characters in double quotes preserves the literal 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 preceding it with a backslash."

Historically, this was not the case. At least as far as I remember. I just 
tested it on my system and the  asterisk is not expanded before being passed 
to find.  I then checked a Solaris system at work and it behaves like this as 
well (*not* expanding the asterisk). I guess there are a lot of UNIX 
old-timers here who are used to the way it **used to** work that we naturally 
assume that it still behaves like that. 

hmmmmm......
