docs/pretty-formats: mention commas in %(trailers) syntax

Commit 84ff053d47 (pretty.c: delimit "%(trailers)" arguments with ",", 2017-10-01) switched the syntax of the trailers placeholder, but forgot to update the documentation in pretty-formats.txt. There's no need to mention the old syntax; it was never in a released version of Git. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
