Sidenote: why not detect violation earlier, by having pre-commit hook
in each developer repository check for such violation?  It is not as
time sensitive on the local side (when creating a commit, you have to
take some time to write commit message anyway).

See how example pre-commit hook check for "non-ascii" file names.
