[PATCH] doc: sha256 is no longer experimental

[Adam Majer <adamm@zombino.com>]

Remove scary wording that basically stops people using sha256
repositories not because of interoperability issues with sha1
repositories, but from fear that their work will suddenly become
incompatible in some future version of git.

We should be clear that currently sha256 repositories will not work with
sha1 repositories but stop the scary words.

-THIS OPTION IS EXPERIMENTAL! SHA-256 support is experimental and still
-in an early stage.  A SHA-256 repository will in general not be able to
-share work with "regular" SHA-1 repositories.  It should be assumed

-repositories may change in backwards-incompatible ways.  Only use
-`--object-format=sha256` for testing purposes.
+Note: At present, there is no interoperability between SHA-256
+repositories and SHA-1 repositories.
+
+Historically, we warned that SHA-256 repositories may later need
+backward incompatible changes when we introduce such interoperability
+features. Today, we only expect compatible changes. Furthermore, if such
+changes prove to be necessary, it can expected that SHA-256 repositories
+created with today's Git will be usable by future versions of Git
+without data loss.
