It is slightly more complicated to match multiple patterns with [[ ]]
because it requires multiple conditions, regexps, or extglob. We could
of course use a bracket expression like [[ ${EAPI:-0} = [012345] ]]
but I find it ugly in this context (and it won't be able to check for
EAPI 10 ;) ).

Besides, case seems to be the command most used for EAPI checking in
eclasses.
