Allow functions that have 1 or more parameters receive and process

multiple arguments when evaluated in a startup file or via one of the
'eval' commands.

This diff does treat the '(' and ')' chars differently during
evaluation than previously, in-so-far as they are not ignored if they
are at the end or start of a line now. However, even though these
characters are not ignored, this diff should not change the behaviour
of an extant .mg file, with '(' and ')' chars at the end and start of
a line.  This situation is accomodated for in this diff (with limited
testing though).
