A look that goes to another pane leaves the looking pane's dot alone

Every look that found something cleared the looker's selection first, so
`@p5:2` or `f.txt:2` written to a pane's look collapsed its dot to
q1-1. Only a look that stays in the pane starts from a clean selection
now; one that goes elsewhere takes away just the click's highlight, and a
miss changes nothing, as acme's look does.
