Provide style file for babel support for Brazilian

[Gustavo Barros]

Hi All,

I'm a native Brazilian and noticed AUCTeX has no support for babel 
language `brazilian', in the form of its proper style file.

I have one here, which I've been using most satisfactorily for quite 
some time (more than a year now), which handles quotes, babel-hyphen, 
some specific macros provided by `babel' etc.  It is not particularly 
complicated.  I'm not absolutely sure it is exhaustive, but it was meant 
to be thorough when I did it.

Unfortunately, I cannot provide it as a patch, since I don't have signed 
papers, and can't have them (I've tried).  But I'd be more than glad to 
provide specific and precise guidance to anyone who could provide a 
patch, and would be willing to take on the task.

Also, though I'm not Portuguese, as far as `babel' is concerned, I 
believe the requirements are very similar, if not identical.  (I'm not 
sure about quotes standards, though).  I could look that up, and check 
things, so that other Portuguese `babel' variants could be provided too, 
even if provisionally, until a proper Portuguese can review it.

Best regards,
Gustavo.
