DumpConfig's lines that set nothing start with #, and a line starting with # runs as nothing at an exec, a ctl or the init file

DumpConfig's information lines ("Platform: tty", "Startup config: ...")
began with words. Written back, as the report means to be, or clicked,
each ran as a shell command or failed as an unknown control message.
Each now starts with `# `. A line starting with `#` is a comment, as in a
shell: it runs as nothing, silently, at an exec, at the root's, a pane's
or a column's ctl, and in the init file. Documented in fs.md and
config.md.
