I always wanted that feature, thanks for implementing it!

If I run `AVOCADO_TAGS="machine:malta arch:mips" make check-acceptance` 
it is going to get the tests with 'machine:malta' *or* 'arch:mips' tags, 
whereas with AVOCADO_TAGS="machine:malta,arch:mips" it gets those with 
'machine:malta' *and* 'arch:mips', i.e., the semantic is different. I 
think it deserves a mention in the docs/devel/testing.rst, maybe linking 
to Avocado's doc [1] as well.
