hyphens and spacing

[Charles Gran]

I'm copying a choral piece and am finding the spacing too tight, I 
want to open it up and also have all hyphens in the lyrics print.  
Can anyone help or direct me to the appropriate sections in docs?

I did find:
\override Lyrics.LyricSpace #'minimum-distance = #5.0
in
7.3.8 Spacing lyrics
but wanted to check if there were other methods (I'm especially 
intereted in the hyphen issue).

Thanks!
Charles
