passing arguments with spaces

[Noel Platzke]

I managed to figure this out with what I'm considering to be a terrible
hack. When the arguments are passed from the service definition to the
command, escaped characters are translated into their unescaped form. So
when I try to pass the argument "this\ is\ a\ string" it becomes "this is a
string" when it's passed to the command. And from there it gets passed to my
script which fails to parse it as a single argument. To address this, I'm
passing the string "this\\ is\\ a\\ string" so that the first time it gets
passed the escaped backslashes are translated into regular backslashes and
then it passes escapes spaces.

Hopefully this will be useful to someone else.
