Re: Proper loglevels: cmd-line option --loglevel=NONE/ERROR/WARN/PROGRESS/INFO/DEBUG (issue4822055)

[hanwenn]

overall commment: the parts that do the reporting should not need to
know about the format of loglevel.

I think it would be better to have a

  if (log(ERROR))
  {
    ..
  }

or perhaps even

  log(ERROR, "...")

rather than having each bit do the bitmasking separately like in this
patch.
