Ref T13164. See PHI766. If you bin/harbormaster rebuild-log ... --force --trace, you can get a trace with a bunch of binary gzip data in it.
This tends to make your terminal beep a lot and sometimes turn into funny colors or symbols.
Instead, replace runs of binary data with the text "<...binary data...>". Also, collapse multiple consecutive whitespace characters into a single whitespace character.
Broadly, both changes make these traces easier to read.
