Adding copyright holders to an MIT-like license

[Sam Hocevar <sam@zoy.org>]

   I was packaging elk for Debian, and also became new upstream because
it was unmaintained. I wonder what I should do with the license (atta-
ched to this message, even if not really necessary). It is an MIT-like
license, and there is no real permission to modify it, but if I am a new
copyright co-holder I should be allowed to add my name to it, right?

   Also the license says "Oliver Laumann (me)". I'd like to remove the
"(me)" part since it's no longer really "him". Is that minor change
allowed?

Regards,
