[PATCH 0/8] Foreign VCS helpers

This is a replacement for the db/foreign-scm series in pu, now based on next. The behavior specified for helpers is the same, so I'm not reposting the particular helpers this time.

Daniel Barkalow (7):
  Use a clearer style to issue commands to remote helpers
  Use a function to determine whether a remote is valid
  Allow fetch to modify refs
  Allow programs to not depend on remotes having urls
  Add a config option for remotes to specify a foreign vcs
  Add support for "import" helper command
  Allow helpers to report in "list" command that the ref is unchanged

Johan Herland (1):
  Allow helpers to request marks for fast-import
