[LAU] jack_disconnect on ports with spaces

Hi list,

I have a script that needs to disconnect various jack connections. Works
fine with client/port names without spaces, like this:

jack_disconnect pure_data_0:output0 system:playback_1

Other port names (specifically, ALSA MIDI port names) however have
spaces in them and don't seem to work with jack_disconnect. Have tried
putting quotes around the names, eg.

jack_disconnect 'Pure Data:PureData Midi-Out 1' 'Hammerfall DSP:HDSP
MIDI 1'

and

jack_disconnect 'Pure Data':'PureData Midi-Out 1' 'Hammerfall DSP':'HDSP
MIDI 1'

Tried double-quotes too as well as underscore characters between the
words but none of these techniques work unfortunately. They result in
error messages like this:

ERROR Hammerfall DSP:HDSP MIDI 1 not a valid port

Nor have i found a way to rename the ports.

Some more detail:

In qjackctl, these ALSA client and port names include numbers. eg.

129:Pure Data

and the port:

1:Pure Data Midi-Out

The HDSP has this too:

20:Hammerfall DSP

and

0:HDSP MIDI 1

I've tried I think all the permutations of names with numbers, numbers
without names and names and numbers together but I can get none to work;

Any suggestions?

Cheers,

Iain
