selection-coding-system description in 21_1_RC etc/NEWS

[Juanma Barranquero <lektu@terra.es>]

This entry from EMACS_21_1_RC's etc/NEWS is inaccurate:

  ** The default value of selection-coding-system is now
  compound-text-with-extensions.

  If you want the old behavior, set selection-coding-system to
  compound-text, which may be significantly more efficient.  Using
  compound-text-with-extensions seems to be necessary only for decoding
  text from applications under XFree86 4.2, whose behaviour is actually
  contrary to the compound text specification.

In fact, the default value of `selection-coding-system' is
system-dependent. On Windows systems, for example, it is iso-latin-1-dos,
while it is compound-text-mac on Macs, I think.
