Ok. Then take what I said as my personal point of view and so also the
little motivation I personally have to work on this.

This includes me as well.
One of the main ideas of open source is that everybody who wants can
contribute and make changes to the code as he/she wishes. I don't
expect anyone to do anything but I also can't implement anything anyone
wishes. My time is limited as well as yours, probably.

I agree but still, there is a difference between what would be nice to
have and what reality is...:(.

It's still another dependency. The goal is to use as less external
libaries as possible. Btw, we already use the regexp implementation of
the C runtime environment (if available) and use the GNU regexp
implementation on all other systems (included in Geany's sources). So,
if this would be enough, we would not need an external dependency.
