Oops, the filtering out code was broken. Now it works again in r42367.

I am not sure if we want that. The idea of parsing the fpc's help
output is to support all available options, including the future ones
added by fpc developers. It does not make sense to analyze their
meaning much.

Important options must have their own dedicated and intelligent GUIs.
The bugs you listed must be fixed obviously.
If someone sets the same option using both a dedicated GUI and the all
options GUI, no problem, the compiler accepts it.

I improved the parser so that -Oo, -OW and -Ow options are selectable
individually instead of a drop-down list.
Only the quoted strings must be handled better, otherwise the parser is OK.
The GUI may be changed to a grid but that is another thing.

Dimitry is working on a competing solution with self made JSON config
files. They are easier to parse but they must be maintained for every
fpc version and architechture. Forgetting the maintenance undermines
the whole idea.
IMO the right place for such info is the fpc project itself.
