** Bug fixes
+ Mistakenly renaming a file onto itself, e.g., via `mv B b' when `B' is
+ the same directory entry as `b' no longer destroys the directory entry
+ referenced by both `b' and `B'. Note that this would happen only on
+ file systems like VFAT where two different names may refer to the same
+ directory entry, usually due to lower->upper case mapping of file names.
+ Now, the above can happen only on file systems that perform name mapping and
+ that support hard links (stat.st_nlink > 1). This mitigates the problem
+ in two ways: few file systems appear to be affected (hpfs and ntfs are),
+ when the bug is triggered, mv no longer removes the last hard link to a file.
+
stat no longer overruns a buffer for format strings ending in `%'
