fix(eval): eros overlay going off-screen

Browse Source 
Evaluating code (and :tools (eval +overlay) enabled) will do one of two
things with the return value:

If long, it will be displayed in a popup window on the bottom of the
frame. If short (<3-4 lines), it will be displayed in an overlay at the
end of the line.

If you happened to have scrolled horizontally (such that the BOL isn't
visible), the overlay would be displayed offscreen and unreadable. Any
attempt to scroll it into view will cause it to disappear (as per its
transient nature). This fix pads each newline in said overlay such that
the overlay is pushed into view.
