Revision e6604c3537e8b60d6cbc821e7d356924c0a0e809 authored by Jonathan Nieder on 02 August 2013, 22:16:40 UTC, committed by Junio C Hamano on 05 August 2013, 15:19:47 UTC
$ git log --encoding fatal: Option '--encoding' requires a value $ git rev-list --encoding fatal: Option '--encoding' requires a value The argument to --encoding has always been mandatory. Unfortunately manpages like git-rev-list(1), git-log(1), and git-show(1) have described the option's syntax as "--encoding[=<encoding>]" since it was first documented. Clarify by removing the extra brackets. Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
