commit: weed out removed w/o recurring to os.path, weed out symlinks

Remove extra if-condition for kwtemplater setup in kwfilelog This was over done in last cset, as repo is None by default kwarg, and None may be tested for attribs.

FIX: make repo keyword arg to kwfilelog hg incoming breaks otherwise as only 3 arguments are passed to init.

Move context into kwtemplater.expand Update kwtemplater doc string.

Overwrite files inside kwtemplater method

Check repo attrib kwfmatcher in kwfilelog init

Parse templates at kwtemplater init for less overhead in matchfunction

Standalone compatibility fixes: demandload, changeset_templater If demandload is present, use it, and import gettext. changeset_templater may have extra arg for branches.
