exchange LyricHyphen with a "proper" hyphen

[Alexander Kobel]

Dear all,

every now and then, I use a font for lyrics where the hyphen is quite 
different from Lilypond's LyricHyphen (in particular, sometimes it's 
slightly slanted). That combined with lyrics where a hyphen has to 
appear looks, well, ugly. (Recent example: a repetition of part of a 
word that has to be written as { ro -- sen-, ro -- sen -- rot }.)

I failed with
  \override LyricHyphen.text = #"-"
  \override LyricHyphen.stencil = #lyric-text::print
trying to replace the LyricHyphen "elementary stencil" by a properly 
printed hyphen from the LyricText font. Did anyone ever successfully try 
to do that, or has an idea how to approach such a tweak?


Thanks in advance,
Alexander
