No, r.region changes the "region" of the raster map itself, i.e. changes
its extent and resolution. The data stays the same. Its changes the
metadata. The effect is stretching, shrinking, or moving the raster map.
Any suggestions for improvement of the manual page?

See r.clip module in addons for equivalent of v.clip:

Best,
