Melchior FRANZ:

Yesterday night it occurred to me that the current handling of missing METAR
strings isn't good enough:

- in case of missing METAR strings, don't re-send the last successful string,
  but the last successful string sent to *this* client. (If one client is
  running in virtual December, it won't be happy about dropped in summer
  weather.)

- fix a bug that allowed -vc notation (options -v and -c), but broke a lot of
  other notations (-b/var/tmp). Only -v can now be accumulated again, as
  in -vvvv.
