Huon Wilson 6072554512 du: make it correct. ... Previously, this was handling symlinks wrong (i.e. `du` was following them, not just looking at them as files). Handling them correctly requires using `lstat`. Also, this would abort when reading a file with invalid permissions (or one that doesn't exist... as a link target of a symlink), rather than just warning and continuing. Also, this patch reduces the number of `stat`s done per file to exactly one (i.e. the minimum).		2014-03-19 18:45:20 +11:00
