bug#6717: tramp-dissect-file-name: Not a Tramp file name

[Michael Albinus <michael.albinus@gmx.de>]

Thanks for the backtrace. The problem is the following line:

  file-name-directory("/index.php?title=%E7%89%B9%E6%AE%8A:%E6%9C%80%E8%BF%91%E6%9B%B4%E6%94%B9&feed=rss")

It checks the local file name part of your URL. Unfortunately, due to
the leading "/" and the ":", it looks like a Tramp file name from
syntactical point of view, but it isn't.

I have committed the following patch towards the Emacs-23 branch (which
will be synchronized with the trunk next days):
