hooks--pre-commit: detect non-ASCII when renaming

Browse source 
When diff.renames is turned on, the diff-filter will not return renamed
files (or copied ones with diff.renames=copy) and potential non-ASCII
characters would not be caught by this hook.

Use the plumbing command diff-index instead of the porcelain one to not
be affected by diff.rename.
