inconsistent doc for call-process-regione

In GNU Emacs 21.3.1 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars)

The doc string for call-process says:

|Insert output in BUFFER before point; t means current buffer;
| nil for BUFFER means discard it; 0 means discard and don't wait.

But later it says:

|If BUFFER is nil, `call-process-region' returns immediately with value nil.
|Otherwise it waits for PROGRAM to terminate
|and returns a numeric exit status or a signal description string.

If I am not wrong, these are contradictory.  If they are not, then I do
not understand, and probably they should be cleared.
