Subject: [PATCH 3/5] inbox: simplify ->description and ->cloneurl
Date: Tue,  4 Feb 2020 04:44:23 +0000
Message-ID: <20200204044425.14031-4-e@yhbt.net> (raw)
In-Reply-To: <20200204044425.14031-1-e@yhbt.net>

We can use "//=" from Perl 5.10 to simplify the logic for these
methods.  The use of chomp() in ->cloneurl was also unnecessary
since split(/\s+/s,...) already removes newlines.
