in d.zoom is some related magic:
display/d.zoom/set.c

...
            fprintf(stderr, "\nResolution is too low for selected region.\n");
            fprintf(stderr, "Buttons:\n");
            fprintf(stderr,
                    "Left:   Increase resolution to n-s = %g e-w = %g\n", nsr,
                    ewr);
            fprintf(stderr, "Middle: Cancel (keep previous region)\n");
            fprintf(stderr, "Right:  Cancel (keep previous region)\n");
...

Maybe something similar is missing in gis.m?
