Tramp and permission denied

Tramp and permission denied

[Lars Hansen]

[-- Attachment #1: Type: text/plain, Size: 245 bytes --]

When I do

   C-x C-f /scp:remote-box:foo

Tramp signals "Login failed" if foo cannot be read due to insufficient
permissions.
With the patch attached, Tramp signals something more descriptive.
I have tested with scp on Debian Sarge only.

Ok?

Maybe I should add: You also get "Login failed" when evaluating e.g.

   (copy-file "/scp:remote-box:foo" "bar")

Here "Login failed" is very misleading.

Please commit.

Maybe the regexp should be expanded depending on messages on other
architectures. I'll check machines I can access (besides Debian it
will be mainly HP-UX); anyway we'll extend when we get other reports.

Thanks for your support, and best regards, Michael.
