That's correct, GNU grep doesn't have that capability (yet).
Recent versions of pcregrep do:
$ echo abc | pcregrep -o1 '.(.).'
b
Thanks for agreeing with the evolution of the meaning of "-o".
Just to make you a laugh: I was reproducing egrep with $BASH_REMATCH:

Definitely not beautiful... but really effective for me.
So something like "egrep -o $n regex" also c
