I've never tried that hook script myself, but it appears to be on the last line:
exec git diff-index --check --cached $against --
In particular, the --check option says:
Warn if changes introduce trailing whitespace or an indent that
uses a space before a tab. Exits with non-zero status if problems are
found. Not compatible with --exit-code.
