Create a new "Git file and wire formats" section in the main "git(1)"
manual page and start moving the documentation that now lives in
"Documentation/technical/*.git" over to it. This compliments the newly
added and adjacent "User-facing file formats" section.
This makes the technical documentation more accessible and
discoverable. Before this we wouldn't install it by default, and had
no ability to build man page versions of them. The links to them from
our existing documentation link to the generated HTML version of these
docs.
So let's start moving those over, starting with just the
"bundle-format.txt" documentation added in 7378ec90e1c (doc: describe
Git bundle format, 2020-02-07). We'll now have a new
gitformat-bundle(5) man page.
Unfortunately the syntax of the current Documentation/technical/*.txt
is not the same (when it comes to section headings etc.) as our
Documentation/*.txt documentation, so change the relevant bits of
syntax as we're moving this over.

+DESCRIPTION
+-----------
+
+The Git bundle format is a format that represents both refs and Git
+objects. A bundle is a header in a format similar to
+linkgit:git-show-ref[1] followed by a pack in *.pack format.
-== Format
+The format is created and read by the linkgit:git-bundle[1] command,
+and supported by e.g. linkgit:git-fetch[1] and linkgit:git-clone[1].
+
+
+FORMAT
+------
We will use ABNF notation to define the Git bundle format. See
-protocol-common.txt for the details.
+link:technical/protocol-common.html for the details.

+Note on the shallow clone and a Git bundle
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Note that the prerequisites does not represent a shallow-clone boundary. The
semantics of the prerequisites and the shallow-clone boundaries are different,
and the Git bundle v2 format cannot represent a shallow clone repository.
-== Capabilities
+CAPABILITIES
+------------
Because there is no opportunity for negotiation, unknown capabilities cause 'git
bundle' to abort. The only known capability is `object-format`, which specifies
the hash algorithm in use, and can take the same values as the
`extensions.objectFormat` configuration value.
