#2783 --script --help when PWD is used shows error

[Jeremy Faden]

You should be able to say --help after a --script command line argument and it should print a help page showing usage of the script. But if the script has PWD, there's a runtime error because PWD is not set.

[Jeremy Faden]

This is fixed, where printScriptUsage in AutoplotUI didn't set PWD.
