Thanks for fixing Richard's and Jakub's comments and parts of mine.

As mentioned before, pleae add a hyphen before fvect (i.e. 
"@option{fvect-cost-model}"  -> "@option{-fvect-cost-model}")

Regarding a test case: I still think it would be useful to have one, but I somehow seemed to have messed up with my previous one - I fail to get it not to vectorize with "omp simd" due to cost reasons. Thus, I don't have one.
