wrong line number when line ends with a semi-colon

the issue is basically the discrepency in reporting the line numbers for these two inputs :

```
julia> a=1
       b=c
ERROR: UndefVarError: `c` not defined
Stacktrace:
 [1] top-level scope
   @ REPL[1]:2

julia> a=1
       b=c;
ERROR: UndefVarError: `c` not defined
Stacktrace:
 [1] top-level scope
   @ REPL[2]:1
```
