 thanks, that passes the 'd.grid 5000' test in spearfish,simple_xy loc'ns +
 latest 6.5svn. no difference with using the 'constrain' tick box in prefs
 AFAICT.

 lat/lon is still reporting meaningless results, in grass7 it should use
 m.measure to do the calc so geodesic distance is automatically used if
 needed.
 (which is basically what I wrote the earlier m.distance.py SWIG version
 for*; see also discussion with Radim in the last week about adding a small
 sleep to QGIS's r.what mouse-over queries so process doesn't get launched
 1000 times per mouse movement)
