#1494 SCI_CLEAR does not delete EOL in multi-edit (multi-caret) mode

[Vic]

Multi-edit mode meant the one you enter with Ctrl+click.
So if you have several carets on empty lines, below shown as vertical segments:

line1
|
line3
|
|
line6

then pressing delete key (bound to SCI_CLEAR if I'm right) does nothing.
The expected result would be:

line1
line3
line6

One can achieve the same end result with the sequence: Arrow-right, Backspace (or SCI_CHARRIGHT, SCI_DELETEBACK).
But it would be more convenient to have SCI_CLEAR work, just like you can delete back with Backspace ( SCI_DELETEBACK) in same situation.

I wasn't sure whether to call it a bug; I guess it's just an omission/ neglected thing?

(I forgot to type the "carets" in the expected result, they would be at front of line3 and line6)

This is to help when lines are of different lengths. Particularly wanted with rectangular selections where you want the selection to remain rectangular.

I think it only makes sense to disable it for rect. selections.
For non-rectangular, the user will be aware (from experience) what the effect will be. Similarly to how backspace is allowed.
