Description of the Issue

Post - #15529 I thought of an improved way to do Python smart-indent: use Scintilla to detect when a colon at the end of a line is styled as a comment, string, etc. Basically, require that its style be "operator" as the colon is defined as an operator in the Python language.

Describe the solution you'd like.

Rely on style context for determining next-line smart-indent, not a somewhat complicated regular expression.
