----------------------------------------------
Forgot to add, the tests TestMultipleOutputs and TestMRMultipleOutputs both
pass with the changes in the previously attached patch.
> Enhance MultipleOutputs to allow additional characters in the named output

> Currently you are only allowed to use alpha-numeric characters in a named
> output name in the MultipleOutputs class. This is a bit of an onerous
> restriction, as it would be extremely convenient to be able to use non
> alpha-numerics in the name too. (E.g., a '.' character would be very
> helpful, so that you can use the named output name for holding a file
> name/extension. Perhaps '-' and a '_' characters as well.)
> The restriction seems to be somewhat arbitrary - it appears to be only
> enforced in the checkTokenName method. (Though I don't know if there's any
> downstream impact by loosening this restriction.)
> Would be extremely helpful/useful to have this fixed though!
