I was looking how nl_langinfo() works, and all it does to help with yes/no 
questions is to return a regex expression (like [^[SsyY].*) to be used to match 
the user's answer, it does not return a string or char value like yes/no (en_US) or 
sim/nao(pt_BR) we can use to replace the y/n in the question string.

The rpmatch() function takes advantage of nl_langinfo() internaly to match the
customer's answer according to which l10n the system is set.

This way, even using nl_langinfo(), the translator person will still need to translate
the y/n to s/n, since is not possible to use nl_langinfo to replace these values.

What we could do, is to create an auxiliar function to check the return of nl_langinfo(),
and, according with this value, write an specific string (s/n, y/n, etc). But, imho, this
could lead to an error prone condition during string creation.

What u think?
