error: add hint to ProgrammingError
As the hint isn't shown by the default exception handler, we need to print
it manually. I've copied the "** " style from _exceptionwarning().
# See http://EditorConfig.org for the specification
root = true
[*.py]
indent_size = 4
indent_style = space
trim_trailing_whitespace = true
[*.{c,h}]
indent_size = 8
indent_style = tab
trim_trailing_whitespace = true
