Some locale related updates

Some locale related updates

[Marko Myllynen]

Hi Michael,

I'll send some locale related updates shortly, most of them should be
pretty self-explanatory but I'll provide some references in few cases
and I'm sure you can come up with slightly better wording here and there.

Related to wording, I see that setlocale(3) states:

The locale "C" or "POSIX" is a portable locale; its LC_CTYPE part
corresponds to the 7-bit ASCII character set.

And
http://pubs.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap07.html#tag_07_02
states:

The tables in Locale Definition describe the characteristics and
behavior of the POSIX locale for data consisting entirely of characters
from the portable character set and the control character set. For other
characters, the behavior is unspecified.

Do you think setlocale(3) is consistent with the above?

Thanks,

I've applied all of the following:

    locale.5: document class in LC_CTYPE
    locale.5: document default_missing
    locale.5: document character transliteration
    locale.5: document map "totitle"
    locale.5: copy is not exclusive in LC_CTYPE and LC_COLLATE
    locale.5: document map to_inpunct, map to_outpunct
    locale.5: document outdigit and alt_digits
    locale.5: document charclass and charconv
    locale.7: LC_CTYPE determines transliteration rules on glibc systems

and also this one that you just sent

    locale.5: fix country_isbn format

Are there more to come?

Help me here ;-). Do you see a problem? If yes, what is it?

Thanks,

Michael

no, that's all, thanks for your superfast response!

Perhaps it's just a language issue, the latter is IMHO somewhat clearer
wrt non-ASCII characters (someone could perhaps interpret setlocale(3)
so that non-ASCII characters are not allowed). I'm ok leaving it as-is,
just wanted to hear your opinion.

Thanks,

I suppose I'd take a patch to improve this.

Cheers,

Michael
