It will not.
1. I did mess up with \@= and \@<= for a reason. Without them regex
will not highlight successive matches.
2. It does not highlight an entire paragraph *ever*. \n\(.*\n\) does
*not* match *only* at the empty line. It matches everywhere where
there are two successive lines.
3. First \{-} does *not* work like you think. In
foo
enabled = True
enabled = False
bar
test
it will highlight starting from the EOL at the first line till EOL
just below bar. Engine captures the first place where \n matches tries
to match the following \(…\)\{-} as less times as possible, then
proceeds with the rest of the pattern. If matching succeeds it has
absolutely no reason to retry from the other place where \n matches
just to make sure \(…\)\{-} is matched even less times.
4. Your regex does not work for sections which are placed at the end
of the file.
5. Your regex works for sections which are placed at the beginning of
the file only because of 2. But it will not work if `enabled = False`
is the very first line in the file.
