The problem with quoting the argument to -c only occurred in composing the output from --print.
So the test failed, but Jython actually worked. In a previous round of change I had simplified processing, thinking I was only interested in making a windows launcher. However, this is now fixed at:
https://hg.python.org/jython/rev/38824a8816a8

This now works on my Linux machine, even when launched as:

$ dist/bin/jython.py -m test.regrtest -e

That way one ends up with sys.executable = 'dist/bin/jython.py' and so it gets used all over the place, not just the launcher test.

I've fixed #2707 in the same change, at least, I've removed the -E for want of anything clever. Circle CI likes us again, but the other CI bots are sulking. I still have to check this with non-ascii paths.
