Environment variables in .subversion/config

Hi,

   I'd like to use a shared config file for multiple users, but I'm in a 
bit of a bind when it comes to ssh identity files.  I'd like to have a 
line like

[tunnels]
ssh = $SVN_SSH ssh -q -i $HOME/.ssh/ssh-identity

   but svn cannot expand environment variables (or ~) from this file.

Warning: Identity file $HOME/.ssh/ssh-identity not accessible: No such 
file or directory.
svn: To better debug SSH connection problems, remove the -q option from 
'ssh' in the [tunnels] section of your Subversion configuration file.
svn: Network connection closed unexpectedly

   It would seem I can only have lines like

[tunnels]
ssh = $SVN_SSH ssh -q -i /home/user1/.ssh/ssh-identity

   which prevents a shared config.

   Has anyone run across this before?  How did you get around this?

Thanks

BTW, have you tried

	[tunnels]
	ssh = $SVN_SSH ssh -q -i ~/.ssh/ssh-identity

?

This works nicely, thank you.  I tried both $HOME and ~, but the client 
doesn't resolve either.

Untested, but:

	[tunnels]
	ssh = $SVN_SSH sh -c 'ssh -q -i $HOME/.ssh/ssh-identity "$@"' -s

or perhaps leave ~/.subversion/config untouched and use the following in
~/.ssh/config:

	Host *
		IdentityFile ~/.ssh/ssh-identity
