lib/strftime.c bug for %r

[Daniel Yacob]

Greetings,

I found that the "date" utility was not displaying the format defined
in locales properly for %r (aka t_fmt_ampm).   The 'r' case at line
1173 in coreutils-5.0 seems to be the problem.  There is no
"goto underlying_strftime;" statement as seen for the related
%c, %x, %X cases.

The "if" statement in the 'r' case seems a little suspect too, but
I don't know what the _NL_CURRENT is about.

Please look into, I tested with the following snippet and it worked
as I was expecting (defferred to the locale):


# if HAVE_STRFTIME
        goto underlying_strftime;
# else
        subfmt = L_("%I:%M:%S %p");
# endif


thanks,

/Daniel
