FIXME:
1. (DONE) If you write '''Б'''ез, it transliterates to '''B'''jez instead of
'''B'''ez, as it should.
2. (DONE) Convert ъ to nothing before comma or other non-letter particle, e.g.
in Однимъ словомъ, идешь на чтеніе.
3. (DONE) Make special-casing for adjectives in -го and for что (and friends)
be the default, and implement transformations in Cyrillic rather than after
translit so that we can display the transformed Cyrillic in the
"phonetic respelling" notation of {{ru-IPA}}.
4. (DONE) Convert apostrophe to ъ before transliteration when after a consonant
and before a vowel (requested by Atitarev).
