mr_IN locale: Fix yesstr and nostr and improve yesexpr and noexpr.
* localedata/locales/mr_IN (LC_MESSAGES): Fix yesstr and nostr
and improve yesexpr and noexpr. The yesstr and nostr apparently
came from CLDR. And CLDR has a bug there: these strings contain
a U+0903 (which looks like a colon) instead of a real colon
to separate the full words for “yes” and “no” from the single
letter responses.
