Breath Marks in Lyrics?

[Walt North]

 I use lilypond to enter music notes, chords, and lyrics and use those 
to create different handouts for different musicians. For those that 
receive melody lines I can insert breath marks.

The rhythm guitarist just wants lyrics and chords.  Is there any tidy 
way to insert breath marks in lyric lines? That don't look like 
apostrophes and don't take up time?
