gpg.program::
Use this custom program instead of "gpg" found on $PATH when
making or verifying a PGP signature. The program must support the
override a value from a lower-priority config file. An explicit
command-line flag always overrides this config option.
+push.recurseSubmodules::
+ Make sure all submodule commits used by the revisions to be pushed
+ are available on a remote-tracking branch. If the value is 'check'
+ then Git will verify that all submodule commits that changed in the
+ revisions to be pushed are available on at least one remote of the
+ submodule. If any commits are missing, the push will be aborted and
+ exit with non-zero status. If the value is 'on-demand' then all
+ submodules that changed in the revisions to be pushed will be
+ pushed. If on-demand was not able to push all necessary revisions
+ it will also be aborted and exit with non-zero status. If the value
+ is 'no' then default behavior of ignoring submodules when pushing
+ is retained. You may override this configuration at time of push by
+ specifying '--recurse-submodules=check|on-demand|no'.

Whether to show a diffstat of what changed upstream since the last

explicitly exposing it, even if an earlier entry marked it as hidden.
If you have multiple hideRefs values, later entries override earlier ones

+If a namespace is in use, the namespace prefix is stripped from each
+reference before it is matched against `transfer.hiderefs` patterns.
+For example, if `refs/heads/master` is specified in `transfer.hideRefs` and
+the current namespace is `foo`, then `refs/namespaces/foo/refs/heads/master`
+is omitted from the advertisements but `refs/heads/master` and
+`refs/namespaces/bar/refs/heads/master` are still advertised as so-called
+"have" lines. In order to match refs before stripping, add a `^` in front of
+the ref name. If you combine `!` and `^`, `!` must be specified first.
