A terminal's Tty word names its shell, Tty+fish, and a click on it opens another

A terminal's tag said Tty whatever shell it ran. The host's acknowledgement
of the shell it forked now sets the word to Tty+<shell>, tinted like the tag's
name. Word+arg is taken as Word arg, one word a tag can hold and a click can
take whole (+ is a word character), so Tty+fish opens a terminal on fish, as
Tty fish does; Tty takes the shell as its argument, which the host forks for
that pane instead of the configured one. Every snapshot whose screen shows a
terminal's tag changes: 69 goldens, re-recorded by name, whose 297 changed
lines are all Tty becoming Tty+bash (the harness runs bash), the cursor
columns and style spans that moved with it, or that text cut at a pane's
width.
