Pansharpened images are not properly stretched

Thanks for the good work and easy to use tool

I am facing a problem with pan sharpening. Pan sharpened images have reduced visual enhancement in comparison to images processed without --pansharp option (see http://tinypic.com/view.php?pic=ndsmcn&s=8#.Vd8fYmBHfuc , pan sharpened image on the left)

Would appreciate any help in the matter

P.S. I have the most up-to-date landsat-util on Mac Yosemite

Reproduce the reported Landsat 8 result on the latest available landsat-util using the --pansharp option, and compare it with processing without that option as described in the issue. Trace the pansharpening and image-stretching entry points to identify where the visual enhancement diverges. Done means pansharpened output has the expected stretch and visual quality, with a regression check for both processing paths.
