Maybe there should be a single message when any number of pending
breakpoints are resolved?  Anyway, one issue at a time.

No, I agree that looks silly.  I meant:

That'll produce:

No symbol table is loaded.  Use the "file" command.
Make breakpoint pending on future shared library load? (y or [n]) y
Breakpoint 1 (main) pending.

Of course that still looks wrong.  It's not a shared library load that
we're waiting for.

Anyone else have concrete suggestions for these messages?
