[PATCH 0/3] Support relative path in <blah>:path syntax

Sorry Jonathan I lied. I did not pick up your fast-import changes. Could not find how to test it. And it seems fast-import only cares about commits, not the target audience of this syntax.

Document is not updated because I think it's intuitive enough.

  setup: save prefix (original cwd relative to toplevel) in
    startup_info
  Make prefix_path() return char* without const
  get_sha1: support relative path ":path" syntax
