references can be a comma separated list, so

A, B, and C

is actually three tags:  "A" "B" "and C"

so, you run into parsing problems, so how to deal with:

[A, B, and C]

maybe:

[{A, B, and C}]

alas, in comma separated list the first level of {} is removed but we 
can cheat:

[{{A, B, and C}}]

works with \cite [{{A, B, and C}}]
