[ruby-core:54784] Call setlocale(LC_ALL, "") instead of setlocale(LC_CTYPE, "")

Hi!

Why isn=E2=80=99t setlocale called with LC_ALL instead of LC_CTYPE in main.=
c?

I have a faint recollection that I=E2=80=99ve discussed this earlier, but I
couldn=E2=80=99t find it in the archives.  I did find the following bug
report, though:

> Issue #1528 has been updated by Shyouhei Urabe.

> Without any setlocale call programs should explicitly behave as in "C" lo=
cale.  No matter of luck are involved in it.

> Historically Ruby has suffered bugs and pitfalls around locales.  I do no=
t want them to raise from the dead, and sticking onto "C" locale is a secur=
e way to prevent that.

I hope that this, four years later, isn=E2=80=99t true anymore and that you=
=E2=80=99ll
change LC_CTYPE to LC_ALL.

If motivation really is necessary, then, for example, strcoll won=E2=80=99t
produce results in the user=E2=80=99s chosen locale if the call to setlocal=
e
doesn=E2=80=99t include LC_COLLATE.
