RunAsDaemon=1 reported as "Unneeded torrc entry"

arm version 1.4.5.0 (released April 28, 2012) Tor v0.2.3.25 (git-3fed5eb096d2d187) Both under Ubuntu Precise.

arm complains:

[ARM_NOTICE] Unneeded torrc entries found. They've been highlighted in blue on the torrc page.
   - entry matches its default value: RunAsDaemon (line 4)

I have RunAsDaemon set to 1, and docs at https://www.torproject.org/docs/tor-manual.html.en say (Default: 0).
