Subject: [RFC] viewdiff: do not break out of DSTATE_CTX on /^$/
Date: Fri, 26 Apr 2019 07:48:32 +0000	[thread overview]
Message-ID: <20190426074832.14686-1-e@80x24.org> (raw)

It seems a common case for mangled patches is editors or MUAs
dropping trailing whitespace, and lines matching /^ $/ gets
the space dropped to only match /^$/.
