[RFA/RFC] New command: ``start''

[Michael Elizabeth Chastain]

Uh, sorry I didn't throw in my two cents earlier, but I am
confused by one clause in this paragraph:

  Some programs contain an elaboration phase where some startup code is
  executed before the main program is called.  This depends on the
  languages used to write your program. In C@t{++} for instance, class
  constructors are executed before @code{main} is called.  It is therefore
  possible that the debugger stops before reaching the main procedure.
  However, the temporary breakpoint will remain to halt execution.

I don't think 'class constructors' is right here.  It's more like
'constructors for static and global objects'.

Other than that, the new doco looks great to me.
