OK, thanks.  I wonder how the heuristics could be improved.  Given
that a lyric hyphen must be preceded by whitespace, while normally
`--` as an articulation is following a non-whitespace character, maybe
a look-behind assertion for the latter would help?  Something similar
could be done for numbers.
