Faults injected one at a time found four that the vectors let through:
R2 at 32 segments, R3 counting code points instead of UTF-16 code units
in an astral NFD, U+036F kept by normalizeWords, and DEL let through by
checkWords. The generators now write both sides of each limit: 32 and 33
segments, 255 and 256 bytes in letters of two and four bytes, 255 and 256
UTF-16 code units of NFD and 252 and 258 from astral decompositions,
bases of 8 and 9 runes, extensions of 3 and 4 also astral, the first and
the last mark of U+0300 to U+036F and their neighbours, and U+001F,
U+007E, U+007F, U+0080 and U+00A0 in a word. All four faults are caught
now.
wordKeyPassword is the password P of spec §38.1, as wordKeySalt is S, and
wordKey uses both: the tests compiled to JavaScript check P against the
one of Go, so that a wrong separator of the words is caught there too,
not only by the keys of 600 000 iterations on the VM.
