You make a good point. But I'm a little nervous about following symlinks and changing permissions on some distant file. Also, the bug that we are trying clean up after would not have created a symlink in this place, so I think the cleanup is not so important if "config" is a symlink. So I suggest that we stick with lstat(), but add S_ISREG(st.st_mode) to the && chain above.
