After re-reading this, I am wondering if the "made multivalued"
above need to be made less confusing.  For a variable that is single
valued, the usual "the last one wins" rule is applied---it's not
like

    [user] 
	name = astian
	name = gitster

makes user.name "gitster" while

    [user] 
	name = astian
    [user]
	name = gitster

makes user.name "multivalued".  In either case, the last one wins,
and it comes not from the syntax but from the semantics assigned to
the variable in question.  What we want to say is not "multi-valued",
but the above two forms both mean the same thing.

But perhaps I am needlessly worried about possible confusion too
much.  I dunno.

Thanks.
