Tramp ignoring ~/.ssh/config

Tramp ignoring ~/.ssh/config

[suvayu ali]

Hi,

I don't know since when, but today I noticed tramp is ignoring
username for remote hosts specified in my ~/.ssh/config

This is with Emacs 24

    Fix indentation

Any ideas?

PS: Emacs 23 works fine.

Could you, please, provide a test scenario for reproducing the problem,
starting with "emacs -Q"?

Best regards, Michael.

To reproduce this I did the following:

1. emacs -Q
2. turn on debug-on-error and debug-on-quit
3. try to open a remote file like this,
   `C-x C-f /ssh:remotehost:~/.bash[TAB]'
4. This prompts me for password like this,
   "Password for /ssh:localuser@remotehost: "

I have attached the backtrace I got from the above. (the real remote
host and local user have been changed to "remtoehost" and "localuser")

In my ~/.ssh/config, the settings for the particular remotehost is like
this:

Host		    	remotehost
HostName	    	remotehost.example.com
User		    	remoteuser
