"git format-patch --range-diff=... --notes=..." did not drive the
underlying range-diff with correct --notes parameter, ending up
comparing with different set of notes from its main patch output
you would get from "git format-patch --notes=..." for a singleton
patch.
* kh/format-patch-range-diff-notes:
format-patch: handle range-diff on notes correctly for single patches
revision: add rdiff_log_arg to rev_info
range-diff: rename other_arg to log_arg
