Surprise! "du -x non-DIR" would print nothing.
Note that the problem arises only when processing a non-directory
specified on the command line. Not surprisingly, "du -x" still
works as expected for any directory argument.
When performing its same-file-system check, du may skip an entry
only if it is at fts_level 1 or greater. Command-line arguments
are at fts_level == 0 (FTS_ROOTLEVEL).
* src/du.c (process_file): Don't use the top-level FTS->fts_dev
when testing for --one-file-system (-x). It happens to be valid
for directories, but it is always 0 for a non-directory.
* tests/du/one-file-system: Add tests for this.
* NEWS (Bug fixes): Mention it.

** Bug fixes
+ du --one-file-system (-x) would ignore any non-directory specified on

mv now lets you move a symlink onto a same-inode destination file that
has two or more hard links. Before, it would reject that, saying that
they are the same, implicitly warning you that the move would result in
