Handle pasting code from column selection specially

Tried column selection in VSCode 1.0. Well, rectangular selection does work, cutting and pasting back also works, but that's about it.
Cutting and pasting into a different part of the code does not work as expected. Both Notepad++ and VS remember that copied text was a rectangular block and paste it as a rectangular block.
VSCode treats copied block just like a regular text, so pasting it anywhere outside of the current multi-cursor context would create a mess.
It's good that the feature is being worked on, but it's not fully baked yet.

This is (still) the current behavior of VS Code. The copied/pasted text matches the selection:

However, the copied/pasted text should match this selection:

See also #43145 for how other editors handle it.

copy/paste rectangular blocks is a regular occurrence eg, to duplicate some text to create 2 columns (and the 2nd column to appear starting from whatever floating top left the cursor is at (even beyond the nominal line ending)
To go from

something a
something bb
something cccc

to

something a        a
something bb       bb
something cccc     cccc

[when the line count, text length/complexity high it is an essential feature in a code editor of substance as many others have commented in the original column select issue]

I would definitely like this feature. There was some talk of it in #1515 but that issue seems to have been closed before it was resolved.
