+/* Stack for prompts. Each prompt is composed as a prefix, a prompt
+   and a suffix. The prompt to be displayed at any given time is the
+   one on top of the stack.  A stack is necessary because of cases in
+   which the execution of a gdb command requires further input from
+   the user, like for instance 'commands' for breakpoints and
+   'actions' for tracepoints. In these cases, the prompt is '>' and
+   gdb should process input using the asynchronous readline interface
+   and the event loop.  In order to achieve this, we need to save
+   somewhere the state of GDB, i.e. that it is processing user input
+   as part of a command and not as part of the top level command loop.
+   The prompt stack represents part of the saved state. Another part
+   would be the function that readline would invoke after a whole line
+   of input has ben entered. This second piece would be something
+   like, for instance, where to return within the code for the actions
+   commands after a line has been read.  This latter portion has not
+   beeen implemented yet.  The need for a 3-part prompt arises from
+   the annotation level. When this is set to 2, the prompt is actually
+   composed of a prefix, the prompt itself and a suffix. */
+
+/* At any particular time there will be always at least one prompt on
+   the stack, the one being currently displayed by gdb. If gdb is
+   using annotation level equal 2, there will be 2 prompts on the
+   stack: the usual one, w/o prefix and suffix (at top - 1), and the
+   'composite' one with prefix and suffix added (at top). At this
+   time, this is the only use of the prompt stack. Resetting annotate
+   to 0 or 1, pops the top of the stack, resetting its size to one
+   element. The MAXPROMPTS limit is safe, for now. Once other cases
+   are dealt with (like the different prompts used for 'commands' or
+   'actions') this array implementation of the prompt stack may have
+   to change. */
