The issues would be due to the issues I mentioned in reply to your
patch on the mailing list. The fixed length string and number of
arguments issues.
In the interests of moving forward, I put the binary shim in front of
the shell script which can make the environment manipulations more
easily.

The version of the code above seems to work, I ran some tests
specifically on ubuntu1804.
I added in some comments so we know in future why the code is doing
this.
I wondered if we could make that script MIT license rather than GPL-2.0
just to try and keep our licensing fractionally simpler?
Cheers,
Richard
