$::FORM is deprecated and getting removed (and will probably actually be 
gone in 2.20 if we get lucky).  Don't use it unless you have an old 
enough version of Bugzilla that doesn't have Bugzilla->cgi available.

If you have that old of a Bugzilla, then %FORM holds single strings, 
which anything that passed multiple values concatenated together. 
%MFORM contains arrays of all of the values for anything that passed 
multiple.

If you have Bugzilla->cgi available, you can get multiple values with 
something like

my @array = Bugzilla->cgi->param('paramname');

You can of course do:

my $cgi = Bugzilla->cgi;

first and then use $cgi if you want (if the file you're working in 
doesn't already do that).
