- the depth of hierarchy du can process is no longer limited by
the user's stack size (nftw uses recursion, the fts implementation
doesn't)
- - works even when run from an inaccessible directory (FIXME: add test)
+ - works even when run from an inaccessible directory
- du -D now dereferences all symlinks specified on the command line,
not just the ones that reference directories (FIXME: confirm
this, and add a test)
- du now accepts -P (--no-dereference)
- du -H now has the POSIX-required meaning (it's equivalent to -D;
before, it was equivalent to --si)
+ - Use O(N) heap space (not O(N^2)) for a hierarchy of depth N.
