provide parsed python patterns and options to pre- and post- hooks.

python hooks receive two new keyword arguments:
- pats: a list of parsed patterns
- opts: a dictionary of parsed options; unsepcified options are set to their defaults

shell hooks receive two new variables containing the string reprentations of the above data:
- $HG_PATS
- $HG_OPTS
