Maybe not dropped, but probably tweaked for DWIM-ness.

Maybe:

  If somebody wants a Maildir to dump JSON search results in they
  could use "-o ./json" or "-o json/" or "-o /path/to/json".

  "-o json" (no slashes or colons) would mean JSON output to stdout.


But then, "json" could be the name of an existing directory,
so if it exists...

Part of me thinks its too magical...

On the other hand, maybe only requiring the colon: "-o json:"
is enough to disambiguate and isn't too much typing.

We'll just assume nobody would want to end a directory
with ":".  They can still use "-o maildir:/i/like/colons:"
if they really want to end a dirname with ":" for whatever
reason...
