rhg: Group values passed to every sub-command into a struct The set of which values this is is evidently not stable yet, so this will make changes easier. Also it is growing, and the function signatures are getting out hand. Differential Revision: https://phab.mercurial-scm.org/D10003

This test file aims at test topological iteration and the various configuration it can has.

  $ cat >> $HGRCPATH << EOF
  > [command-templates]
  > log={rev}\n
  > EOF

On this simple example, all topological branch are displayed in turn until we
can finally display 0. this implies skipping from 8 to 3 and coming back to 7
later.
