Thanks, Roy.  For anybody who might have already grabbed
a copy of the code, please grab it again, because the CGI
program ("search") has just been changed a bit -- I replaced
the pipe-open with the much safer fork-open + exec that
bypasses any shell involvement and possible nasty exploits
that could result.
I was afraid that someone out there might turn off the
"clean_spec" code that was protecting against unexpected
shell expansion, and thus open a security hole.  The new
version is totally immune to such problems.
