Hi Michael,
i'd like to provide Tramp support for this new Dired feature.
The implementation is fairly straight: just adds a function
'insert-directory-wildcard-in-dir-p' in files.el, and use it in
'insert-directory' and Dired.
To get Tramp support i've added a handler
'tramp-sh-handle-insert-directory-wildcard-in-dir-p'.
Is this procedure OK or i am doing something weird?
Best regards,
Tino

Dired: Handle wildards in directory part
Allow to Dired to handle calls like
\(dired \"~/foo/*/*.el\"), that is, with wildcards withing
the directory part of the file argument.
* lisp/files.el (insert-directory-wildcard-in-dir-p): New predicate.
(insert-directory)
* lisp/dired.el(dired-internal-noselect)
(dired-insert-directory): Use it.
* /etc/NEWS: Announce it.
* doc/emacs/dired.texi (Dired Enter): Update manual.
