It writes the whole thing as one vector, should we require the caller to reshape to clearly identify it as a vector? Then anything with multiple columns could be written as a matrix (e.g. by internally calling sparse()).
I cannot remember why I defaulted to this behavior. (Probably for people using DMDA and automatically reshaping a read in vector into its DMDA defined shape and then later wanting to save that as a vector). I guess it might be more intuitive to change it as you suggest.
It was a size mismatch in that case anyway, so I chose this rather than an implicit reshape. Dense row and column vectors are both written as vectors. http://petsc.cs.iit.edu/petsc/petsc-dev/rev/03d36104f143
