IF not, the obvious one is to have a known section (such the [general] or
the default) where N is defined. Or, loop from n=1 to read blockn until you
get an exception saying the section doesn't exist. Or limit the number of
blockn sections allowed (to, say, 100), and just loop over all n=1 to N=100,
skipping those that lead to exception (ie section not defined, in case not
contiguously numbered).
