work and will produce hard-to-diagnose issues.
+extensions.compatObjectFormat::
+
+ Specify a compatitbility hash algorithm to use. The acceptable values
+ are `sha1` and `sha256`. The value specified must be different from the
+ value of extensions.objectFormat. This allows client level
+ interoperability between git repositories whose objectFormat matches
+ this compatObjectFormat. In particular when fully implemented the
+ pushes and pulls from a repository in whose objectFormat matches
+ compatObjectFormat. As well as being able to use oids encoded in
+ compatObjectFormat in addition to oids encoded with objectFormat to
+ locally specify objects.
+
extensions.refStorage::
Specify the ref storage format to use. The acceptable values are:
+
unfortunately named tag "master"), and shows them as full
refnames (e.g. "refs/heads/master").
+--output-object-format=(sha1|sha256|storage)::
+
+ Allow oids to be input from any object format that the current
+ repository supports.
+
+ Specifying "sha1" translates if necessary and returns a sha1 oid.
+
+ Specifying "sha256" translates if necessary and returns a sha256 oid.
+
+ Specifying "storage" translates if necessary and returns an oid in
+ encoded in the storage hash algorithm.
