Subject: [PATCH 30/34] watch: enable autoflush for STDOUT and STDERR
Date: Sat, 27 Jun 2020 10:03:56 +0000	[thread overview]
Message-ID: <20200627100400.9871-31-e@yhbt.net> (raw)
In-Reply-To: <20200627100400.9871-1-e@yhbt.net>

In case output is redirected to a pipe, ensure stdout and stderr
are always unbuffered, as -watch may go long periods without
any output to fill up buffers.
