[REQUEST] Another extension to append comma

[christhofer]

This extension is very useful, I have been using it for years.

There is already an extension to append comma at the end of the line, but it doesn't work for multiline cursor, and the creator has not responded to the issue for after 2 years.

But this extension can append semicolon to multiline cursor, and detects if the line already has semicolon.

Would be great if you make separate extension for comma.

Thanks in advance.
