Changes in release 4.1:
[4.0r]
+* install -d may now be used to set special bits
+ e.g., `install -m a=rwx,o+t -d DIR' now honors the `o+t' part
+* cp, mv, ln, install: document that while the --backup option takes an
+ optional argument, the -b option accepts none
* `ls -e' fails with a more useful diagnostic
* df produces better output for loop file system mount points
[4.0q]
* cp, install, ln, mv: deprecate the --version-control option. Use --backup's
new optional argument instead. The old option still works, but now evokes a
warning.
+* cp, install, ln, mv: the --backup option now accepts an optional argument
* cp, install, ln, mv: accept new option: --target-directory=DIR
* chgrp: accept new option, --dereference. --no-dereference is now the default.
* New ls option --quoting-style=locale acts like --quoting-style=c, except
