Yes, it does. Everything between EXEC SQL and the semicolon is SQL by
definition, the rest is C.

I don't agree. Please keep in mind that ecpg can spit out illegal C-code as it
is now. It accepts and outputs nested comments that the C compiler obviously
does not accept. Or in other words, I cannot see that people have code that's
broken by the change I made.

BTW I did notice that the patch is incomplete, though. I need to add another
another check or the nested comments still get put into the C file.

I'm absolutely willing to check and update the docs, but didn't so far because
I see this as a bug that got fixed and not a new or changed feature.

So far there is nothing about comments in the docs at all AFAICT. I'd expect
people to expect standard C behaviour.
