add comment explaining a subtlety

Tony caught a bug I made in d5a00e4af6b155495be31a35728b8fef8e671ebe and fixed
it in 2dc40b2d7c20b0d31c4343ac23cda9799f234a65. This comment explains
the subtlety that lead to the bug: the compilation state var
RExC_npar is +1 as compared to the equivalent rex->nparens.
