Git is not an archiver. Git does not track directories at all, including empty directories.

It would be nice if this could be done (where possible -- see Jakub's reply) before install already, so people looking at your install do not have to look at ../../../../.. and remove five path components by hand. There shouldn't be a problem doing it at file open time as you say (unless we wand to support users putting .. in the paths themselves, instead of just our make system doing that :-) ) Segher
