Isn't it a bug to pass '\n' to maybe_colorize_sideband() ?

This will escape DEL ('\x7f') as "^\xbf" which is invalid in utf-8
locales. Perhaps we could use "^?" for that instead.

I'd be happier if we used test_cmp() here so that we check that the
sanitized version matches what we expect and the test does not pass if
there a typo in the script above stops it from writing the SGR code for red.
