[PATCH] confusion with overlapping grammar errors

Hi,

I was asked to post my patch from
https://bugs.freedesktop.org/show_bug.cgi?id=49605 here:

Problem: having two grammar errors that partly overlap confuses writer, it 
will show the same error message for both. I think that's because only the 
first error is considered, as the error's end position is ignored. The 
attached patch seems to fix this.

See the issue for a description of how to reproduce this. Feedback is 
welcome.

Regards
 Daniel
