* src/debug/dbgentry.c
+ added protection against wrong parameters passed to __dbgDelBreak()
* src/debug/debugger.prg
+ implemented display history for command window.
This modification also fixes clearing command window when focus is
changed.
+ added support for new commands:
DELETE ALL BP
DELETE BP <nNumber>
LIST BP
* replicated Clipper compatible command line shortcuts
! send :RefreshAll instead of :RefreshCurrent to source code window
when break point changed
; TODO: add support for window resizing and repositioning. Commands
like LIST BP are in practice unusable in 3 line command window.
