Shell, editor and terminal configuration, and the tools that go with them 

tmux: the command prompt gets an opaque background

Every theme set message-style with a bg and no fill. From tmux 3.7 the command
prompt is drawn over the status line, where only the prompt's own characters
take that bg and the rest of the line takes fill; with status-style bg=default
everywhere here, the terminal showed through around the prompt. Reported from a
machine running 3.7c.

fill now matches bg in all eight. It has existed since tmux 3.2 and older
versions ignore it, so this is safe on the fleet: checked on 3.5a, where each
theme sources cleanly and reports the fill back.
