[bug-mailutils] pick missing the "--" feature for matching arbitrary components

[Joe Brenner]

I have a number of shell scripts that do mail refiling in the
traditional "mh" way, where I often do things like this:

  refile `pick +inbox \
        -from           address@hidden \
    -or -to             address@hidden \
    -or --apparently-to address@hidden \
  ` +BALUG

The Gnu utils version of pick does not seem to know what to
make of something like "--apparently-to", it gives me the
error:

  pick: unrecognized option `--apparently-to'

With nmh, the double hyphen indicates you're matching a mail
header field (aka a "component") with some arbitrary name, in
this case: "Apparently-to:"
