improved lyrics handling

[Werner LEMBERG]

I want this:

  text = \lyrics {
    "\textit{Er:}~Ge" -- denkst ...
  }

But Lilypond doesn't like this.  Is there currently a way to get font
changes?

My suggestion: Handle "..." and '...' differently; the former is
interpreted by LilyPond, the latter isn't (similar to bash).  The user
shall be responsible for providing a proper width for the string;
using my suggested \wide and \wwide (or \width{...} as a generalized
extension) this should be quite easy.

The alternative would be to collect all strings enclosed in '...', do
a TeX run with special macros and use the returned metrics.
