Fix some more docstring etc. quoting problems

Fix some more docstring etc. quoting problems

Mostly these fixes prevent the transliteration of apostrophes
that should stay apostrophes.  Also, prefer curved quotes in
Bahá’í proper names, as that’s the preferred Bahá’í style and
these names are chock-full of non-ASCII characters anyway.
