[tex-hyphen] Fwd: Polyglossia + Serbian Cyrillic hyphenation

[Karl Berry]

    Does it mean that hyphen.cfg loads the two files consecutively?

Looking at \process at language in hyphen.cfg, it appears so.  Should
probably look at the doc instead of the code, though :).

In any case, whatever babel is doing, would it be possible to have
hyph-utf8 generate one file, say loadhyph-sr.tex, which reads both -latn
and -cyrl?  Putting two files on a line in language.dat is unprecedented
and would need numerous changes throughout the infrastructure.
