Hi,

This patch fix http://sourceware.org/bugzilla/show_bug.cgi?id=15165

But I didn't use commands because it is not current way to setup
commands of dprintf.

So I add a check in save_breakpoints to let it not save dprintf
commands..  If you think we need, I can put commands save code as a
special function to handle it.

Please help me review it.

Thanks,
Hui
