           Summary: Better 'expected ';' at end of statement diagnostic
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Keywords: quality-of-implementation
          Severity: enhancement
          Priority: P2
         Component: parser
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: clattner at apple.com

Consider this erroneous program:

void foo() {
  int X;
  X = 4
}

We currently emit:

t.c:4:1: error: expected ';' after expression
}
^

This is ok as far as basic stuff goes, but the caret diagnostics would be much
nicer if the caret was pointing to the end of the previous line (right after
the 4) instead of at the }.  This happens very frequently if you forget a ;.
