Not AFAIK. You want to match anything that is not opening parenthesis and stop when you hit one. This is usually what you mean. and I started doing the non-greedy ones out of habit.

But matching the last parenthesis is not bad anyways. Maybe I will just end up using the regexp you wrote for ld (which I started with, and foolishly thought I could improve).

what do you think about my addition of ^$, could this cause any issues? This is also just regexp habit from my side

I have a hard time seeing filenames/sections with : and ( being well defined. and in that case a more general escaping mechanism would be necessary anyways, and that would probably be much clearly expressed in code, and not a regexp.
