Yes, grafting sounds really very promising! - I did not know about it.

It's probably too tight limitation for regular developers; for random hackers contributing a patch or two it could be a choice, right.

Indeed, this is the case of URE - it is supposed to run by separately & be used even by other projects than OOo.

And this would be interesting for the translations, I guess...

Thank you and others for all the input!

Last question: what is the status of the Win32 support? I got a full clone using the Cygwin git 1.5.0 [it took 6hrs 20min on a Xen virtual machine; I have to try it with real hardware], MinGW version did not work for me too well :-( Are there any other options? Is http://git.or.cz/gitwiki/WindowsInstall up-to-date?
