Subject: [PATCH 7/8] configure: quote command line arguments in config.status
Date: Thu,  7 Jan 2021 15:00:38 +0100	[thread overview]
Message-ID: <20210107140039.467969-8-pbonzini@redhat.com> (raw)
In-Reply-To: <20210107140039.467969-1-pbonzini@redhat.com>

Make config.status generation a bit more robust.  (The quote_sh
function will also be reused to parse configure's command line
arguments in an external script driven by Meson build option
introspection).
