[PATCH v2] pre-commit hook should ignore carriage returns at EOL

When commit files that use DOS style CRLF end-of-lines, the pre-commit hook would raise an error. When combined with the fact that the hooks get activated by default on windows, it makes life difficult for people working with DOS files.

This patch causes the pre-commit hook to deal with crlf files correctly.
