[feature] Support for pasting current line/selection as a comment above/below

[AniAggarwal]

I find myself often copy-pasting a line or selection and then commenting out the original so that I can make some changes but still preserve the original if I want to revert. I'd love if there was native support for this as I've tried to create a mapping but it's been quite janky.

Example usage:

pr|int("just some code here that I want to change but preserve")
foo(bar)

> gcp with cursor anywhere on first line

# print("just some code here that I want to change but preserve")
|print("just some code here that I want to change but preserve")
foo(bar)

Similar behavior with selections, with gcp pastes below and gcP pastes above and gbp and gbP doing the same but with block comments.

Sorry, must have missed it! I can't quite get that one to work though (I'll comment on that thread).

There is also a discussion thread about the same (or create one?). Please follow that instead of commenting on a different issue.
