Terminal emulators gained a capability called "bracketed paste" where
they send a control sequence (similar to pressing a function key) at
the start of a paste, and a different control sequence at the end.

Oliver added ZLE widgets to recognize those two control sequences, plus
ZLE startup/shutdown actions that tell the emulator to enter/leave the
"bracketed paste mode" so that it will invoke the widgets.

You could previously do this yourself with zle-line-init/zle-line-finish
plus two other user-defined widgets, but the change makes it built-in
and automatic.
