[Request] [+- ] D10390: outgoing: pass subrepo path using function argument instead of abssource hack

REVISION SUMMARY
  This is clearer, remove the needs for the `repo._subtoppath` hack and will make
  our live easier when making `outgoing` accept multiple destinations.
  
  We needed a new function to compute the appropriate "relative" location.

REPOSITORY
  rHG Mercurial

BRANCH
  default
