Thanks for doing this but I'm concerned that a change of this magnitude
is too much for post rc5 of a release, assuming you were intending to
propose this for 4.3 with a view to getting it backported to 4.2. We
don't generally take stuff directly into 4.2.

If someone could find a targeted fix to the JSON parsing then that has a
much higher chance of acceptance, I think.

If we are going to rewrite this code for 4.4 (which is something I think
I would support!) then I think it might be better to do it as "xl
autosave" and "xl autorestore" rather than continuing to try and parse
either JSON or SXP from a shell script (which is just a losing
proposition really).

Ian.
