           Summary: coverage merge should detect changed source code

           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: druntime

Just to not merge numbers from different versions of the same source file.
Could be implemented very simply by storing a hash/modtime of the source
somewhere in the coverage report (e.g. on the first/last line).
