I just used the URI style because that is what Mozilla uses on the
command line, but if that is an uncommon usage it makes sense to use
/path/to/file instead.  I also surrounded the attachment file list
with single quotes as per the Mozilla specification.  I should
probable get rid of those as well.  The attachment portion of the
mailto string will change from

&attachment="'file:///path/to/file1,file:///path/to/file2'"
to
&attachment="/path/to/file1,/path/to/file2"
