One Look path: Enter, Tab and a bare Look take what a click at the cursor takes, a diff line's address included, and an event reader is told of them as of a click

The keyboard expanded the cursor's word on its own (look.expandedSel), so
a diff line's address (and a hunk line's code word, without its +/-) was
the mouse's alone: Enter on `+line` looked for the text in the diff. Now
exec.operandAt is the one expansion: pointerOperand is it with a gesture's
selection borrowed, the Enter/Tab path and a bare Look (exec.currentOperand)
are it from the cursor, and both dispatch through mouse.dispatchPointerBuiltin,
so a pane with an event reader hears a key's look or exec as a click's.
A test runs one diff line and one file:12:5: line through a B3 click, a B3
sweep, Enter, a bare Look, the look file and an event write-back, and asserts
each lands in the same file, line and column.
