Subject: [PATCH] better getVersion when working on a darcs tree
getVersion tries to find the date of the latest applied patch from
_darcs/inventory - this patch makes it only read the last 2000 byte
of the file instead of loading the whole file.
darcs-hash:20060916182955-7ad00-5a38de1ae4f1a206a8f62cc88551d4f0bc35340e.gz
