Matching username in ssh_config

[Anton Lundin]

Hi all openssh devs out there.

I have quite a few Host-stanzas in my .ssh/config to keep track of all the
different settings and credentials needed to access all different hosts I
connect to.

Now I have ran in to a problem where I need to switch settings based on what
user I'm trying to login to a host as. A simple case is:

ssh -i rootkey root at host123
vs. 
ssh -i userkey username at host123

Up until now I have just used a stanza like

Host host123
 User username
 IdentityFile userkey

But it would be awesome of it was possible to add before that, eg fist
match as all other blocks, a stanza looking like:

Host root at host123
 IdentityFile rootkey


So when I type:
"ssh host123" it resolves to equivalent of "ssh -i userkey username at host123"
And when i type:
"ssh root at host123" it would resolve to "ssh -i rootkey root at host123"


Does this sound reasonable to the rest of you?
