Interesting.  I didn't know about the environment stuff, I just used it
to type commands.  For reference, here's the OpenBSD implementation (for
sh):

. file [arg1 ...]
        Execute the commands in file in the current environment.  The
        file is searched for in the directories of PATH. If arguments
are
        given, the positional parameters may be used to access them
while
        file is being executed.  If no arguments are given, the
position-
        al parameters are those of the environment the command is used
        in.


Cheers,

James
