I introduced ‘--’ as escape sequence in 
https://github.com/textmate/dialog/commit/fcb4f30fefe46fb423d5dc6ac4c07ee8eaab3dea

That means you can use:

     "$DIALOG" tooltip --text -- "--Pitch"

The problem is that the option parser does not have any template, so it 
does not know that --text expects an argument, instead it looks at the 
next string provided, to decide wether --text is a boolean or key/value 
option.

We should change it so that each subcommand provides the parser with an 
option template. With such template to guide the parsing, the escape 
sequence I just introduced may become invalid (as we would ideally use 
getopt_long rather than roll our own, and getopt_long does not support 
‘--’ between an option and its argument).
