Unable to pass option value with spaces in them to ecl run

I want to pass a #option value via the command like with -f , where the value had spaces in it.
But it seems the argument processing breaks the quoted strings at spaces, treating them as multiple arguments.

e.g.

$ ecl run -g --cluster=thor -fsaveCppTempFiles=1 -fapplyInstantEclTransformations -fapplyInstantEclTransformationsLimit=100 '-ftestopt=hello there' t.ecl
Error: File 'there' does not exist
