I am getting a "replace-regexp-in-string: Invalid use of ‘\’ in replacement 
text"
error using 'shell-quote-argument' on this case.

It seems that 'shell-quoted-argument' is adding double '\', that is,
'\\', in front of the spaces instead of surrounding the argument with quotes.

And 'replace-match' which is called by 'replace-regexp-in-string' for the 
parameter
substitution ("%i", "%o") in the function 'dired-do-compress-to' doesn't like 
it.
