keyword: safeguards against erroneous behaviour or aborts

prevent issues due to global [keyword] filename patterns:
- add email to nokwcommands
- protect everything under .hg from expansion
  (tested with qcommit)
- exclude everything starting with .hg* just in case

prevent abort when pulling from bundlerepo:
- do not set up kwrepo for bundlerepo
  expansion inside a bundle is nonsense

bundlerepo issue spotted and test case provided by pmezard.
