url-default-expander expands wrongly on Windows

url-default-expander expands wrongly on Windows

[Klaus Straubinger]

In GNU Emacs 22.2.1 (i386-mingw-nt5.1.2600)
 of 2008-03-26 on RELEASE
Windowing system distributor `Microsoft Corp.', version 5.1.2600

the function url-default-expander calls expand-file-name which
inserts interesting but wrong drive letters into URLs when called
on Windows.

In my opinion the local part of an URL should not be handled by
file-name handlers at all.

Can you please provide a test case for reproducing the problem. As far 
as I can see, url-expand-file-name is the entry point for calling this 
function, but I can't find a URL that causes it to fail in the way you 
describe.

(url-expand-file-name "test" ["http" nil nil "www.gnu.org" 80 "/" nil nil t])

--> "http://www.gnu.org/c:/test"

The URL should not be relevant as long as something is provided in the
DEFAULT argument.

Can you show an example so as to help us understand the problem?

I do not understand what you're talking about.
