-/* 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. */
