notes.mergeStrategy::
	Which merge strategy to choose by default when resolving notes
	conflicts.  Must be one of `manual`, `ours`, `theirs`, `union`, or
	`cat_sort_uniq`.  Defaults to `manual`.  See "NOTES MERGE STRATEGIES"
	section of linkgit:git-notes[1] for more information on each strategy.

notes.<name>.mergeStrategy::
	Which merge strategy to choose when doing a notes merge into
	refs/notes/<name>.  This overrides the more general
	"notes.mergeStrategy".  See the "NOTES MERGE STRATEGIES" section in
	linkgit:git-notes[1] for more information on the available strategies.

notes.displayRef::
	The (fully qualified) refname from which to show notes when
	showing commit messages.  The value of this variable can be set
	to a glob, in which case notes from all matching refs will be
	shown.  You may also specify this configuration variable
	several times.  A warning will be issued for refs that do not
	exist, but a glob that does not match any refs is silently
	ignored.
+
This setting can be overridden with the `GIT_NOTES_DISPLAY_REF`
environment variable, which must be a colon separated list of refs or
globs.
+
The effective value of "core.notesRef" (possibly overridden by
GIT_NOTES_REF) is also implicitly added to the list of refs to be
displayed.

notes.rewrite.<command>::
	When rewriting commits with <command> (currently `amend` or
	`rebase`) and this variable is set to `true`, Git
	automatically copies your notes from the original to the
	rewritten commit.  Defaults to `true`, but see
	"notes.rewriteRef" below.

notes.rewriteMode::
	When copying notes during a rewrite (see the
	"notes.rewrite.<command>" option), determines what to do if
	the target commit already has a note.  Must be one of
	`overwrite`, `concatenate`, `cat_sort_uniq`, or `ignore`.
	Defaults to `concatenate`.
+
This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
environment variable.

notes.rewriteRef::
	When copying notes during a rewrite, specifies the (fully
	qualified) ref whose notes should be copied.  The ref may be a
	glob, in which case notes in all matching refs will be copied.
	You may also specify this configuration several times.
+
Does not have a default value; you must configure this variable to
enable note rewriting.  Set it to `refs/notes/commits` to enable
rewriting for the default commit notes.
+
This setting can be overridden with the `GIT_NOTES_REWRITE_REF`
environment variable, which must be a colon separated list of refs or
globs.
