touch: often I want to protect myself from myself

[Dan Jacobson]

The touch info file does talk about permissions, but it seems not to
talk about the case when I can reset the modification time despite
permissions,

$ whoami
jidanni
$ ls -l a
-rw-r--r--    1 jidanni  jidanni      4370 2004-08-21 03:15 a
$ chmod 0 a
$ touch a
$ ls -l a
----------    1 jidanni  jidanni      4370 2004-08-21 06:15 a

just because it's mine. So perhaps mention it.
$ ed a
a: Permission denied

That's better.
Often I want to protect myself from myself.
