Re: [PATCH 3/9] docs: reflect actual double signature for tags

 Signed Tags
 ~~~~~~~~~~~
+We add new fields "gpgsig" and "gpgsig-sha256" to the tag object format to

Not suggesting a change in the text, but to make sure I am reading
the new text correctly.  Does "the other algorithm" refer to the
compatibility hash algorithm specified by the compatObjectFormat
extension and the "current" algorithm refers to the objectFormat
extension?

My reading of the previous paragraph is that we cannot have gpgsig
and gpgsig-sha256 fields on a single object at the same time.

Should we say "gpgsig or gpgsig-sha256" (instead of "and"), to get
the resulting text parsable as:

	both 
		its gpgsig or gpgsig-sha256 fields
	and
		"-----BEGIN PGP SIGNATURE-----" delimited in-body signature
	removed.

instead?

+"-----BEGIN PGP SIGNATURE-----" delimited in-body signature removed.
 
-1. using SHA-1 only, as in existing signed tag objects
-2. using both SHA-1 and SHA-256, by using gpgsig-sha256 and an in-body
-   signature.
-3. using only SHA-256, by only using the gpgsig-sha256 field.
+This means tags can be signed using one or both algorithms.
