Start universal $Hg$ keyword expansion

Rename parent1 to p

Rename lr variable to repo

Adapt to filename instead of basename style

Short "f" for "filename" iteration variable

Added tag filename for changeset 56a61a5c696d

Switch to complete filename in first keyword field This will hopefully allow to iterate over the stream in hgkwdecode, and lookup the relatively latest revision of corresponding file.

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
