I've added a patch to master which allows quoting the local part of the
file name. Maybe you could rewrite your patch, using this feature.

There are also three new functions tramp-quoted-name-p, tramp-quote-name
and tramp-unquote-name. Maybe it is worth to expose them more generally,
as file-name-quoted-p, file-name-quote and file-name-unquote.

Best regards, Michael.
