Subject: [Makefile] Add support for pandoc 2 and disable smart extension (closes #16251)
X-Git-Url: http://git.bitcoin.ninja/index.cgi?a=commitdiff_plain;h=af751350e8651f665333554fa13b335b073fa736;p=youtube-dl

[Makefile] Add support for pandoc 2 and disable smart extension (closes #16251)
smart extension rewrites straight quotes as curly quotes, -- as en-dashes and so on that is unwanted behavior.
