+/* 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. */
