When certain types of error messages are converted to strings, certain schema properties are incorrectly converted about jsonschema

[Julian]

There's nothing converted there, in Python (like in C) "foo" "bar" is a single implicitly concatenated string.

The behavior comes from pprint which is what we use for formatting output, but making this nicer is #243 which you're of course welcome to chime in on.

It is not just about making it "nicer" the current output is ,because of this behaviour of pprint unusable.

The other thinng that you could consider to make the output of pprint usefull is to set width=sys.maxsize as per this stackoverflow article: https://stackoverflow.com/questions/31485402/can-i-make-pprint-in-python3-not-split-strings-like-in-python2

Again this is not just a cosmetic issue, this is also a usability issue.
