From: Max Reitz Date: Fri, 19 Oct 2018 16:49:28 +0000 (+0200) Subject: object: Make option help nicer to read X-Git-Tag: v3.1.0-rc0~8^2~3 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=da3273adcde967b53de6bb6d6b4af607cbccff8a;p=thirdparty%2Fqemu.git object: Make option help nicer to read Just like in qemu_opts_print_help(), print the object name as a caption instead of on every single line, indent all options, add angle brackets around types, and align the descriptions after 24 characters. Also, indent every object name in the list of available objects.
