obsfate: makes successorsetverb takes the markers as argument

Right now, successorsetverb only needs successors to compute the verb. But we
will want use additional information (effect-flags and operation) in the near
future to compute a better verb.

Add the markers parameter now so extensions (like Evolve) could wrap the
function and start experimenting around better obsfate verbs.

As successorsetverb now takes both successorset and markers parameters, rename
it to obsfateverb, successorsetandmarkersverb was too long.

test non-zero exit of shell command

we don't fix up relative file URLs, but we do run shell commands in repo root

  $ mkdir sub
  $ cd sub
  $ hg log -qr "extdata(filedata)"
  abort: error: The system cannot find the file specified (windows !)
  abort: error: No such file or directory (no-windows !)
