Comment:

 Some ideas:


 * ''Some kind of step over or next...''[[BR]]
 Isn't :steplocal or :stepmodule it? Looks like already done.


 * ''We can disable a breakpoint with...''[[BR]]
 A breakpoint which has a code attached to it should not print anything not
 printed by the attached code. Well, except the command prompt printed if
 the attached code does not issue :continue. This would be handy. I asked
 for it also in my comment to #2737. If this is not done then custom
 implementation of features like conditional breakpoint or breakpoint setup
 solely to monitor value changes (an alternative to printf debugging) spit
 out a lot of garbage. The garbage can be suppressed but that suppresses
 also the legitimate program output. If you implement this then
 implementing flag for disabling breakpoints (a point later on) is not
 needed.


 * ''if a :force results in a breakpoint...''[[BR]]
 :force hitting a breakpoint should either print more information about the
 breakpoint or it should not print anything at all. The current situation
 is the worst one (it does something in the middle :) ). See also #2950.
 Anyway, I like the fact that :force does not stop at breakpoints. This
 ticket #2946 is related to :force too.
