Generalize the protection of brackets in citation arguments

Browse Source 
Whenever an argument delimiter is used inside the argument, the argument
needs to be grouped, that is

\cites({text (text) text})

or

\cite[{text [text] text}]

This fixes the original case reported in #2751 which is independent
from the general issue that the pre- and postnote field take literal
code.
