If we aren't looking for an exact addr vs. line match in findline(), and

the addr is before the first source addr, let's assume it's legit and
return the first source line.  This prevents the obnoxious 'second number
must be greater than first' message after 'func foo; list' and function foo
is the first function in the file.
