Helper.pl parses comments, too

[czurnieden]

If you comment about the intricacies of sizeof in a comment, helper.pl reacts with
[sizeof_no_brackets]
See for example line 55 in bn_mp_n_root_ex.c in #189 (changed now, was a single sizeof before)
Can you change it @karel-m without much work or shall we just put a line or two in the documentation?
