Use localrepository's wjoin() to obtain absolute path

Use wfile instead of wopener; read and write string not binary

FIX: range of status selection; copyfile using absolute path

Add pretxnkw module for updatehook branch

Add pretxnkw module for commits

updatehook branch: add kwexpander and updatekw modules WARNING: Do not use this branch for production! Update hook changes to working directory are detected by hg. The only /hook/ to escape hg's attention seems to be pretxcommit. And that probably only due to bug. Kept branch for archiving purposes.

decodefilter branch: add decode filter with kwutil module

Make pattern compilation local to function

Shorten variable and function names

Add simple [encode] filter in python The aim is to go for $Hg$ without basename. Perhaps this is feasable with update hooks &Co. No way to detect a filename while stream writing. Even though hg /knows/ the filenames, but does not provide an API or hook, unfortunately.
