[Documentation] uneven '*' character --> Error '*' expected

[mratsim]

I'm trying to use nim doc on a file with a dependency on @andreaferretti Nimcuda.

nim doc fails for any line with uneven number of star characters. As far as I know nimcuda documentation is autogenerated by c2nim and have a lot of such:

cublas_api.nim(139, 52)

  ##  cublasSetVector (int n, int elemSize, const void *x, int incx, 
  ##                   void *y, int incy) 

cuda_occupency(265, 4)

##  If *blockSize is 0, then the given combination cannot run on the device.

Error is:

Error: '*' expected

The doc gen uses reStructuredText. Fix your documentation.
