Would that be useful?

Here's how I envision this command being useful: the context-sensitive
analysis I described earlier.  Heuristics (i.e. guesses) as to what's
happened to the file, while GDB's back was turned.  The user's rarely
going to know "oh, that breakpoint moved twenty lines".

The alternative command, "oh, that breakpoint should be over here now",
is a lot simpler for a CLI user to use.  Maybe it's still useful?  I
didn't think so originally, but I'm being persuaded.
