detect {opensql} and {stop} sections

detect {opensql} and {stop} sections

this so that I can still have
{opensql} and {stop} sections in non-console python.

this isn't the norm but I would prefer if I dont have to
be 100% strict about it

also maintaining {sql} / {stop} being at the start
of a code line.  this is more prevalent in 1.4.
