z-sy-h implements something like this to be able to highlight command
positions throughout $PREBUFFER and $BUFFER.  Specifically, z-sy-h's
parser knows at any point what the last command word was and what are
the $BUFFER start and end offsets of the current shell word.

Even without RC_QUOTES, the binding «''» collides with the «'\''»
sequence for embedding a literal single quote in a single-quoted string.
