  SVN rev 223742 on 2011-07-03 16:32:03Z by jilles
  
  MFC r223227: rc.subr: Eliminate about 100 forks from the boot sequence.
  
  With the current sh, placing eval in a command substitution always results
  in a fork(), even if it is the only command and only executes a single
  simple command. Therefore, avoid it where it can be avoided easily.
  
  Side effect: values starting with a hyphen and all whitespace are preserved.
  The values are defaults and names for rc.conf variables and messages to be
  given about obsolete ones.
  
  The change in the _echoonce function is not included in this MFC because
  stable/8 does not have this function.
