If I understand, you have DEM tiles in one projection (location) and
you're trying to use r.proj to transform the tiles into a different
location. If that's the case, typically you would use the r.proj flag '-g' to get the region settings in the target location from the raster extent in it's source location. So you might do something like: g.region -p `r.proj -g loc=<source location> map=<source mapset> input=<source dem>` then run r.proj without the -g flag and you should get the reprojected raster. Finally, once you have all the tiles reprojected, use g.list raster pattern=<....> sep=comma to get a list of all the tiles, then g.region -p rast=<list of tiles> to set the computational region to cover all tiles. One additional point: consider to patch all DEM tiles together in their native projection *first* then project the single patched DEM once to the target projection.
