Subject: [PATCH] convert: describe the release of fast-import pipes
Date: Wed, 20 May 2020 07:38:08 +0000 [thread overview]
Message-ID: <20200520073808.27837-1-e@yhbt.net> (raw)
Upon rereading the code, it wasn't immediately obvious to
me why we didn't check for errors with `close($w)' instead
of relying on `undef'. So add a comment for the benefit of
future readers.
