Subject: [PATCH] config: do not slurp lines into memory
Date: Thu,  9 Feb 2017 00:27:12 +0000
Message-ID: <20170209002712.24300-1-e@80x24.org> (raw)

There's no need to hold everything in memory, here,
since apparently "foreach" will read everything at
once in array context

(for some reason, I thought Perl5 was smart enough
 to avoid creating a temporary array, here...)
