I hadn't payed attention to the "user-defined commands" point.
Francois and I have had a look at such things a little while back
and found that the CDT also does not handle user-defined commands
properly.  Sourcing a script also causes the same issues.

We were discussing a type of "full-refresh" once a script is parsed,
so as to get DSF synched with the changes caused by the console script.
This may not be possible for user-defined commands though if we cannot
tell that a user-defined command has just been run.
Does GDB have some differentiating output after a user-defined command?
