Imported TIFF exhibits bogus color fringing
The attached TIFF contains a white grid on grey background. It only contains shades of grey. However, imported in Darktable, the grid lines become full of colours. This can also be seen in export.

That's a duplicate of #9699, isn't it?
darktable treats these kind of TIFFs (1 color channel, 16 bpp, EXIF data indicating maker and model of a camera) as RAW files. What you see are the
consequences of color interpolation.

Right, darktable seems to fail when it comes to detecting grayscale TIFF images. Not sure though if fixing that might break other things,
expecially correclty dealing with those RAWs that come as TIFFs (ancient Canon cameras, Phase One).
