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...

... but will have a better look; thanks for the pointer!

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?

Jan
