In 2D, it works OK.

However, the 'l' hotkey is completely broken in 3D. It should (un)log both Z 
and CB axes, not only one of them. The hotkey 'L' should be selective to Z 
or CB according to position of the mouse cursor -- it's ok now.

Another broken example:

gnuplot> set pm3d map
gnuplot> splot x*x+y*y+1
gnuplot>          y range has y coord of -10; must be above 0 for log scale!

I.e., the 3D hotkey functionality for 'l' should work as before the patch, 
while the 'L' works correctly now.
