Per Regents of the University of Calfornia letter, remove advertising
clause.

# If I've done so improperly on a file, please let me know.

- If the directory to be removed has its immutable, undeletable or append-only
flag set, rmdir(2) returns EPERM.
- If the parent directory of the directory to be removed has its immutable or
append-only flag set, rmdir(2) returns EPERM.

Back out the previous change to rename.2. The previous rename()
behaviour of returning EINVAL when ".." is passed as either argument
has been restored.

rmdir("..") now returns EINVAL instead of EPERM. Document the
previously undocumented behaviour of rmdir(".") returning EINVAL
as required by POSIX and SUSv3. Bump the man page change date.

undelete("..") now returns EINVAL instead of EPERM. Bump the man
page change date.

MFC after: 3 days

rename(), rmdir(), and undelete() fail with EPERM if the last component
of the path is "..".

mdoc(7) police: "The .Fa argument.".

mdoc(7) police: Tidy up the syscall language.

Stop calling system calls "function calls".

Use "The .Fn system call" a-la "The .Nm utility".

When referring to a non-BSD implementation in
the HISTORY section, call syscall a function,
to be safe.

mdoc(7) police: Use the new .In macro for #include statements.

Use the ``.Rv -std'' mdoc(7) macro in appropriate cases.

mdoc(7) police: removed HISTORY info from the .Os call.

Prepare for mdoc(7)NG.

Use `Er' variable to define first column width in ERRORS section. It was
initially suggested by mdoc(7) style, but was broken over the years

Introduce ".Lb" macro to libc manpages.

More libraries manpages updates following.

$Id$ -> $FreeBSD$

Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

.\" $Id$
.\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

Remove the EINVAL error from the ERRORS sections that
say is means that a pathname had the high-order bit
set, since this is no longer an error.

Correctly use .Fn instead of .Nm to reference function names
in a bunch of man pages.

Use the correct .Bx (BSD UNIX) or .At (AT&T UNIX) macros
instead of explicitly specifying the version in the text
in a bunch of man pages.
