cat <<'EOF'
Whitespace issues found. We can't fix in a pre-commit hook for the first commit.
Either fix on your own. I suggest https://github.com/dlenski/wtf, from git root:
-find . -not -name .git -type f -exec bash -c \
- 'grep -Il "" "$1" &>/dev/null && wtf.py -i -E lf "$1"' _ {} \;
+
+git ls-files --exclude-standard -cmo --no-empty-directory | while read -r f; do if [[ -L $f ]] || ! grep -Iq . "$f"; then continue; fi; wtf.py -i -E lf "$f"; done
+
or allow whitespace with:
git config hooks.allowwhitespace true, or export GIT_ALLOWWHITESPACE=true
