[PATCH] hooks--pre-commit: detect non-ASCII when renaming

From: Julian Prein <redacted>

Currently the diff-filter that is used to check for non-ASCII characters
in filenames only checks new additions.

Extend the diff-filter in the pre-commit sample to include `CR` as well.
This way non-ASCII character in filenames are detected on a rename/copy
as well.
