messes up links and file permissions #5

Apparently jpegoptim writes its output to a temporary file and uses rename(2) to move it back to the original. This breaks hard- and symlinks and changes the permissions of the file.

File permissions are now preserved. And symbolic links (and other special files) are skipped to avoid "breaking" symlinks. Behavior with hard-linked files is now documented on the man page.
