I think so. Either this, or ask the user to choose. I think the current
situation is partly historical: In C, the situations where this happens
are rare...

This is because you may have several instances of the same line. Imagine
that you have an inlined function defined at foobar.c:12. The function
body is duplicated at each call of the function. If the user asks to
insert a breakpoint at this line, which instance/address should the
debugger use?
