Patch which implements the functionality described above.

When chrooting users it can be useful to be able to use a user's group
name as a parameter when constructing the chroot directory path for a
user. The code already supports parameter expansion for the user name
(%u) and home directory (%h).

So, this can be implemented by a fairly simple extension of the
existing code. I have attached a patch which adds the parameter %g
which expands to the user's group name if used in a ChrootDirectory
configuration line in sshd_config. E.g.  ChrootDirectory 
/opt/domains/%g  If user foo with group bar connects via ssh then they
will be chroot'd to /opt/domains/bar
