etc/NEWS: set-mark-command-repeat-pop incorrectly documented

[Mark H. Weaver]

In etc/NEWS of the Emacs 22.1 distribution, the new 
set-mark-command-repeat-pop feature is described twice.  The second 
description is incorrect, because it does not mention the variable 
`set-mark-command-repeat-pop', but merely assumes that it's set to t,
although its default value is nil.

etc/NEWS lines 283-286:

** A prefix argument is no longer required to repeat a jump to a
previous mark if you set `set-mark-command-repeat-pop' to t.  I.e. C-u
C-SPC C-SPC C-SPC ... cycles through the mark ring.  Use C-u C-u C-SPC
to set the mark immediately after a jump.

etc/NEWS lines 453-455:

*** A prefix argument is no longer required to repeat a jump to a
previous mark, i.e. C-u C-SPC C-SPC C-SPC ... cycles through the
mark ring.  Use C-u C-u C-SPC to set the mark immediately after a jump.
