Subject: Remove the CONFIG_FEATURE_SH_APPLETS_ALWAYS_WIN option.  It was
 sortof stupid and didn't work properly anyways.

-	  Use a command builtin to the shell over one with the same name,
-	  that may be on the system.
+	  This option causes the selected busybox shell to use busybox applets
+	  in preference to executables in the PATH whenever possible.  For
+	  example, entering the command 'ifconfig' into the shell would cause
+	  busybox to use the ifconfig busybox applet.  Specifying the fully
+	  qualified executable name, such as '/sbin/ifconfig' will still
+	  execute the /sbin/ifconfig executable on the filesystem.  This option
+	  is generally used when creating a staticly linked version of busybox
+	  for use as a rescue shell, in the event that you screw up your system.
