Thanks for noticing and sorry for the bug. I thought it was behaving 
correctly since a lot of English variants were listed and unfortunately 
did not notice that some of them were missing, my fault. I really wonder 
how no one found this before.

This change was introduced to deal with portuguese, that has no pt.dat, but
pt_BR or pt_PT. 

I am currently playing with attached patch, that tries different .dat
matches. This should be better than before, and deal with former case plus
portuguese. Will test a bit more and commit if no problems appear.
