1. Steps to reproduce:

Compile this .vala file
---------------------
int main(){/*1*/r}
---------------------

Bug applied only to case where comment placed in one line. I've attached patch to fix it.


2. Got result
---------------------
test.vala:1.16-1.16: error: syntax error, expected identifier
int main(){/*1*/r}
               ^
Compilation failed: 1 error(s), 0 warning(s)
---------------------


3. Expected result:
---------------------
test.vala:1.18-1.18: error: syntax error, expected identifier
int main(){/*1*/r}
                 ^
Compilation failed: 1 error(s), 0 warning(s)
---------------------
