detecting mutt version

[Robert Tsai]

Can the .muttrc detect what version of mutt is running? I would rather
not 'mutt -F .muttrc.<version>' depending on the hostname of the
current machine.

I want to use 'subscribe' and 'lists' appropriately, depending on what
version of mutt is being run (which depends on what machine I'm logged
in on, on which I do not want to install my own mutt, for either
administrative or disk quota reasons).
