I'm not so fussed about #1 but #2 would be excellent :)

I hadn't looked yet at TeXworks regexing code for all this.
Looks very promising!

I'm pretty confused by this regex engine. This is the best I can do:

^%[\s]{4}\\(?:begin|end)\{macrocode\}

But that still matches four tabs. Why can't I write ( ){4} or (\ ){4}  
or even [\s^\t]{4} to match four spaces only?
