space character in StopImage path not supported

In exe mode with an stop image command like:

--StopImage "C:\Program Files\scripts\service\stop.cmd"

procrun is unable to stop the service.

The stderr just shows:
"Der Befehl "C:\Program" ist entweder falsch geschrieben oder
konnte nicht gefunden werden."

which translates to:
The command "C: \Program" is either misspelled or
could not be found.

Having a space on StartImage path is working.
