I agree that these are useful features, but I would think they are
more appropriate as part of "catch" implementation for Windows.  For
starters, treating these as catchpoints will allow to use all the
features of catchpoints: ignore counts, commands, display in "info
breakpoints", etc.

So would you like to rewrite this as subcommands of "catch"?  E.g.,
how about

  . catch exception [NAME]

    will stop when a specified exception (default: any exception) is
    detected

  . catch debug-string

    will stop whenever any debug string event is detected.

In any case, these are user-visible changes, so they will require
updates to the user manual.

Thanks.
