Restoring breakpoint failed

Restoring breakpoint failed

[Tom Tromey]

I saved a session that included a breakpoint with attached commands.
When restoring the session, I got the appended error.

I'm pretty sure I tested this functionality when I wrote it, but to be
honest it is so long ago that it is hard to be certain.  Did something
change in `gdb_cmd' to make multi-line commands no longer work?
If so, how can breakpoint command restoration work?

FWIW for me it is very important that sessions work well.
They are the only feature that reliably separates Insight from using
gdb in Emacs (variable display would be another one, but I've learned
not to use that due to its propensity to provoke gdb crashes).

Yes, I know about this. I think the problem is that gdb doesn't allow you
to do this. I certainly haven't found a way to get gdb to allow me to
specify commands without going through readline...

I guess the only thing to do is write new C code for gdbtk.
Unfortunately that's enough work that I definitely can't do it.
Would you like me to submit a PR?

Naw... I'll just jot it down in my todo list. When testsuites get the
better of me, I'll implement it. (Which means don't be suprised if you see
something sooner than later.)
