[inx] <command reldir="path">somecommand -with -arguments</command> fails

[su_v]

Commands with parameters fail when being called directly from an 'inx'-file.

error message:
 Can't Spawn!!! spawn returns: 8
when quitting the application - occurs in 'src/extension/implementation/script.cpp', line 1029
<http://inkscape.svn.sourceforge.net/viewvc/inkscape/inkscape/trunk/src/extension/implementation/script.cpp?view=log>

inx commands that are known to fail:
ai_output.inx: <command reldir="path">gs -q -dNODISPLAY -dSAFER ps2ai.ps</command>
svgz_input.inx: <command reldir="path">gzip -cd</command>
svgz_output.inx: <command reldir="path">gzip -c</command>
(all three extensions have recently been removed from SVN trunk)

I could not figure out (searched in launchpad and inkscape-devel archives) if this was an intended change or a unintended consequence of a patch to handle spaces in the path for extensions on win32 (see bug #187290).

related bug:
Bug #167472 “save as dialogue, duplicate 'Compressed Inkscape SVG' entry”

possibly related bug:
Bug #187290 “[Win32] Extensions not working on Windows with rel 0.46-pre0 ”

Confirmed with recent SVN builds on OS X 10.5 ,XP and Ubuntu (in bug #167472)

The problem here is since we switched to the spawn interface in glib we're no longer passing the command through a shell. We need to parse the command for spaces and add them in the argument list.
