Conflicting mime types

[Jerome Leclanche]

To go back on your original question which is more in line with "what to do
when we get two conflicting globs?":

I think resulting behaviour should be the same as what you would do when
getting two conflicting, same-priority magics. The spec doesn't seem to
advocate a behaviour in this case[1]. In general, if there are conflicts,
they should be solved using the priority attribute at the package level.

It would be a good idea to specify a behaviour when getting such conflicts.
