I don't consider the pretty printers to be stable and feature complete
yet, but I'll take your reply as an objection and so won't go ahead
and commit the change.

I don't think we've settled on a consistent output from the pretty
printers yet, all the options have some flaws.

(Aside, one issue I have with the pretty printers is they
automatically dereference iterators, which is a problem for
past-the-end iterators.)

Mu.

A GDB front end should use one of the programmatic interfaces to get
output from GDB, writing a GUI by parsing text meant for display in a
terminal is doomed to fail in the long run.

But I do think this particular change is reasonable.
