Bug#919047: ssh_config: allow tokens for IdentityFile keyword

[Daniel Baumann <daniel.baumann@progress-linux.org>]

Package: openssh
Severity: wishlist

Hi,

it would be nice if ssh would allow using tokes in ssh_config for the 
IdentityFile keyword to minimize ssh_config files.

Without token, a config might look like this:

  ---
  Host *.example.com
    IdentifyFile ~/.ssh/keys/daniel.baumann@example.com

  Host *.example.org
    IdentifyFile ~/.ssh/keys/daniel@example.org
  --

with token support, I could have:

  --
  Host *.example.com *.example.org
    IdentityFile ~/.ssh/keys/%u@%h
  --

Regards,
Daniel
