Subject: bug#33043: [PATCH v1 1/1] Support for the truncation of displayed URLs
Date: Mon, 15 Oct 2018 11:06:26 +0100 [thread overview]
Message-ID: <20181015100626.2344-1-dme@dme.org> (raw)
In-Reply-To: <cund0sbwmo8.fsf@dme.org>
When applying markup to URLs in the buffer, truncate the visible
portion to `rcirc-url-max-length' characters. By default no truncation
is done.
