Yes, as well as for the case of ``segmented'' dataset.

Allowing multiple rasters to be specified saves one from using a
temporary raster map for the result of `r.series' or `r.patch'.
Also, the calculation of the standard deviation with the help of
`r.series' or some Bash code like the above is hardly an obvious
thing.
