Manipulating lyrics with a music function

[David F.]

macOS 10.14.6, Lilypond 2.22.1

The syntax for adding quotes to lyrics is a little cluttered, so I thought I’d 
whip up a couple of little helper functions to tidy things up.  Two hours later 
I’m reaching out to the mailing list for help.  The example below is failing in 
two ways.  First, I can’t figure out how to actually interpolate the syllable 
that is the input to my functions into the output.  Second, the hyphen between 
the first two syllables is lost.

Help?
