individual synonyms apparently broken

has:
 ADD ADHD HADD
alcohol drinking drunk
assist help
cessation quit
child children kid youth
class lesson
computer technology internet
counseling
utility fuel

so you would think a search on 'drunk' would get you the same results as 'alcohol' , it doesn't

My best quick guess is that

lib-mvhub/lib/MVHub/GuideSearch.pm::expand_synonyms is broken , probably when SYNONYM_STEM_X_WORD_STEM moved into SQL::Library

see:

    :bzr log -r 373 -p lib-mvhub/lib/MVHub/GuideSearch.pm | less

my guess is that placeholders can't take multiple words separated by commas

Adding a unit test with $wordlist would be swell as well
