It's a reference to the entire pattern (giving a recursive match,  
thus the R). It was used as in the workaround for the nested brackets  
problem, e.g. a pattern like: “\\{(?R)?\\}” will match a { and } with  
the entire pattern optionally inside, causing it to match balanced  
brackets.

Oniguruma should have something similar, where one can refer to a  
capture (group), but I haven't been able to make it work.
