We really need to keep it to one set of quotation marks, so it
ought to be something like:

    Attach:foo.txt"%md5 %size"

I just haven't figured out the substitution markup that makes
sense for this.  I can envision doing one of:

    Attach:foo.txt"%md5 %size"
    Attach:foo.txt"$md5 $size"
    Attach:foo.txt"{md5} {size}"

Unfortunately(?), one thing that *won't* work is the page variable
markup, as in Attach:foo.txt"{$md5} {$size}", because page 
variable substitutions take place before Attach: links.  Plus,
it confuses attachments with pages, and people seem to get
those confused enough already.
