+	help
+	  The vi undo functions can use an intermediate queue to greatly lower
+	  malloc() calls and overhead. When the maximum size of this queue is
+	  reached, the contents of the queue are committed to the undo stack.
+	  This increases the size of the undo code and allows some undo
+	  operations (especially un-typing/backspacing) to be far more useful.

+	depends on BUSYBOX_FEATURE_VI_UNDO_QUEUE
+	help
+	  This option sets the number of bytes used at runtime for the queue.
+	  Smaller values will create more undo objects and reduce the amount
+	  of typed or backspaced characters that are grouped into one undo
+	  operation; larger values increase the potential size of each undo
+	  and will generally malloc() larger objects and less frequently.
+	  Unless you want more (or less) frequent "undo points" while typing,
+	  you should probably leave this unchanged.
