[PATCH 0/4] git-am: use trailers to add extra signatures

["Michael S. Tsirkin" <mst@redhat.com>]

I'm using git am to apply patches, and I like the ability
to add arbitrary trailers instead of the standard Signed-off-by
one.

To this end, I have extended git am to call git interpret-trailers
internally. This way I can add arbitrary signatures.

For example, I have:
[trailer "t"]
        key = Tested-by
        command = "echo \"Michael S. Tsirkin <mst@redhat.com>\""
[trailer "r"]
        key = Reviewed-by
        command = "echo \"Michael S. Tsirkin <mst@redhat.com>\""
[trailer "a"]
        key = Acked-by
        command = "echo \"Michael S. Tsirkin <mst@redhat.com>\""
[trailer "s"]
        key = Signed-off-by
        command = "echo \"Michael S. Tsirkin <mst@redhat.com>\""

And now:
	git am -t t -t r -t s
adds all of:
	Tested-by: Michael S. Tsirkin <mst@redhat.com>
	Reviewed-by: Michael S. Tsirkin <mst@redhat.com>
	Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

This was originally suggested by Junio (a long time ago).

Documentation and tests are still TBD.

Michael S. Tsirkin (4):
  builtin/interpret-trailers.c: allow -t
  builtin/interpret-trailers: suppress blank line
  builtin/am: read mailinfo from file
  builtin/am: passthrough -t and --trailer flags
