Fix printing of some wide-characters by iswprint() on ja_JP.eucJP
and ja_JP.SJIS locale

The iswprint() function does not return non-zero if used for
some wide-character that it code was 0x824f-0x8258 on ja_JP.SJIS
and 0xa3b0-0xa3b9 on ja_JP.eucJP locale. But those are right
Japanese wide-character code.

The wcwidth(3) should return 2 about characters in JISX0208 codeset.
But it returned 1.
It fixes the problem reported by many Japanese people that tcsh 6.14
doesn't work correctly with ja_JP.eucJP locale.
