I agree with the first part. There are some places that should be kept
as is. However, the '\<return *([^ ]*)' would generate some false
positives, for example 'return (buf[0] << 0) | (buf[1] << 8)' and few
others I've found.
Don't worry though, I've created a regexp that matches just what's
needed, composing the patch right now.
