*** New customizable variable 'next-error-find-buffer-function'.
-This variable defines the logic of finding a next-error capable
-buffer. It has an option to use a single such buffer on selected
-frame, or by default use the last buffer that navigated to the current
-buffer. You can use 'next-error-select-buffer' to set any other
-next-error capable buffer as the last used.
+The value should be a function that determines how to find the
+next buffer to be used by 'next-error' and 'previous-error'. The
+default is to use the last buffer that navigated to the current
+error.
