This patch puts the usage info strings that were not already in docopt- like format into docopt-like format, which will be a litle easier for end users and a lot easier for translators. Changes include: - Placing angle brackets around fill-in-the-blank parameters - Putting dashes in multiword parameter names - Adding spaces to [-f|--foobar] to make [-f | --foobar] - Replacing <foobar>* with [<foobar>...] Signed-off-by: Alex Henrie <alexhenrie24@gmail.com> Reviewed-by: Matthieu Moy <Matthieu.Moy@imag.fr> Signed-off-by: Junio C Hamano <gitster@pobox.com>
