core: don't hit an assert when printing status messages about units with overly long...

This essentially reverts one part of d054f0a4d451120c26494263fc4dc175bfd405b1.

(We might also choose to use proper ellipsation here, but I wasn't sure the
memory allocation this requires wouöld be a good idea here...)

Fixes: #4534
