Let s, S and | pressed in a tag answer for the tag's own text

A tag is a text like the body, so selecting on a regex and piping act on the
text they are pressed in: a prompt records the text it answers for, the tag
keeps the keyboard while it is typed, and a header's prompt goes on the active
pane's band. `/` still searches the body from anywhere, as acme's Look from a
tag searches the body.
