 > Used r.profile interactively in GRASS 7.1 SVN.  Same problems described
 by stu.  If I use horizontal and vertical units of meters, the plot is
 perfect.  If I change to horizontal and vertical units of feet, the Y axis
 of elevations is displayed correctly, but the X axis is squished to stop
 at the unit value in meters rather than feet.  Example:  I had a 800 meter
 transect, but when reprojected to feet and profiled, the graph stops at
 800 feet rather than the approximate 2600.  The endpoint triangle,
 however, is placed around the 2600 distance.  It's as if it thinks the
 units are meters horizontal.

 Yes, it's meters because meters come from r.profile and the GUI profiling
 tool just takes the values as they are. I wonder if this should be changed
 in r.profile rather than in the GUI?
