Subject: [PATCH 13/11] edit: drop unwanted headers before noop check
Date: Mon, 10 Jun 2019 18:17:08 +0000
Message-ID: <20190610181708.mg2aiazd5adolsn6@dcvr> (raw)
In-Reply-To: <20190609025147.24966-1-e@80x24.org>

mutt will set Content-Length, Lines, and Status headers
unconditionally, so we need to account for that before
doing header comparisons to avoid making expensive changes
when noop edits are made.
