I've been using this for years:

find -L .  -perm /111 -a \! -perm 755 -a -exec chmod 755 {} + -o \
         \! -perm /111 -a \! -perm 644 -a -exec chmod 644 {} +

Instead of listing every possible wrong permission, list the ones that
are correct, with a ! for "not". It's also less code and easier to
read, IMO.
