coreutils/man/rm.x - fails to mention POSIX "Refuse to remove path/. and path/.., as well as `.' and `..'

coreutils 9.3
coreutils/man/rm.x

Even though "rm" was modified,

...
* rm.c (rm): Refuse to remove path/. and path/.., as well as `.' and `..', for 
POSIX.
...
====
the rm(1) man page completely fails to mention this particular POSIX promise.

If the user already knows how GNU rm will respond to "rm -rf *", they don't 
need to look at the man page.

If the user does *not* know how GNU rm will respond to "rm -rf *", the GNU rm 
man page is not going to help them.

Language should be added to the GNU rm man page explicitly stating the POSIX 
behavior:
====
If either of the files dot or dot-dot are specified as the basename portion of 
an operand (that is, the final pathname component) or if an operand resolves to 
the root directory, rm shall write a diagnostic message to standard error and 
do nothing more with such operands.
====
including the additional requirement with respect to the root directory.
