Cannot find it after a short search.  The basic rule is that any
combination of upper- or lowercase letters as well as non-ASCII
characters (so Unicode characters with a character code larger than
127), with isolated - and _ characters allowed inside.

The respective lines in lily/lexer.ll read

A               [a-zA-Z\200-\377]
SYMBOL          {A}([-_]{A}|{A})*
COMMAND         \\{SYMBOL}
