Browse Source

hence determines the notes tree that will be manipulated.  It also
DWIMs a refs/notes/ prefix.

Like '-C', but with '-c' the editor is invoked, so that
the user can further edit the note message.
--ref <ref>::
Manipulate the notes tree in <ref>. This overrides both
GIT_NOTES_REF and the "core.notesRef" configuration. The ref
is taken to be in `refs/notes/` if it is not qualified.
