I understand (I think).  But all this does is fill in the attributes
that were missing from the input location spec.  This is done either
by using the (implied) defaults, like the name of the current file, or
bhy using the debug info.  And if it turns out that some attribute can
be filled in more than one way, we have a breakpoint with multiple
code locations.  Right?
