Make default pre-commit hook less noisy

This hook thought to have found a conflict marker any time it saw a 7-character combination of any of the characters '<>=' at the beginning of a line, whereas it should only look for the *same* character to appear repeatedly.

Also, restrict it to match exactly 7 times, to avoid matching the underlining with '='-characters often used in documentation.

---
As far as I know, this will still properly match all conflict markers, even those by cvs or svn.
