Actually, it's probably better to go directly from the locale, since
locale-language-names doesn't really give the names of languages, it
gives the names of language environments, which can be totally
different.

I see only several locales that will need to dynamically determine
paragraph direction in comint buffers.  Those are locales matching the
following regular expressions:

  \`ar_.*
  \`fa_.*
  \`he_.*
  \`iw_.*
  \`ur_.*
