With the new "key=" option to %(trailers) it often makes little sense to show the key, as it by definition already is know which trailer is printed there. This new "valueonly" option makes it omit the key when printing trailers.
E.g.: $ git show -s --pretty='%s%n%(trailers:key=Signed-off-by,valueonly)' aaaa88182 will show: > upload-pack: fix broken if/else chain in config callback > Jeff King <peff@peff.net> > Junio C Hamano <gitster@pobox.com>
