...That fix was necessary because this: mhshow-show-multipart/signed: sigcheck %a '%F' used to have this effect: mhshow-show-multipart/signed: sigcheck %a ''%F'' which was clearly broken (and noted, but not quite as clearly, in the comments).
thinking out loud here, what if the file name has embedded quotes?
seems like we need a %Q(%F) construct that means, quote if nec'y, add interior backslashes if nec'y.
(this is how $dbh->quote() works in perl code that accesses an SQL database.)
