I don't want Boa to override Pythonwin so I've suggested adding
it as 'Edit in Boa', this is not accessible from ShellExecute I
suppose...

I've now ripped the dde code from Pythonwin and it seems to work,

But multiple files are already separated by spaces.
Unless you choose a better separator (some standard one I don't know), 
it is still ::

e.g.

Boa.py d:\dev\tst.py::42

It will happen after the next release. 
(Btw, *only* the editor is 90% of Boa ;)
