bug#17567: 24.4.50; doc string of `define-derived-mode'

[Drew Adams]

The doc string erroneously says that parameter NAME is "a string
which will appear in the status line".

Emacs does not have a "status line".  That term is used nowhere.

What should be said about NAME is that it defines the value of variable
`mode-name' for mode CHILD.  A user consulting that variable will see
that its value is used in the mode line etc.
