  if test -d .git; then

     # Configure 'git diff' hunk header format.

     git config 'diff.elisp.xfuncname' \
	 '^\(def[^[:space:]]+[[:space:]]+([^()[:space:]]+)' || exit
     git config 'diff.texinfo.xfuncname' \                  ^^^^^^^
	 '^@node[[:space:]]+([^,[:space:]][^,]+)' || exit
						  ^^^^^^^

It exits with an error message, which in my book means it "fails".
