bug#16395: Tab-containing lines displayed with different background?

[Jarosław Rzeszótko]

Hi,

It's #141414 vs #151515, might not be easy to notice depending on
display/brightness/contrast/..., but you can zoom in and probe with
Gimp or something and you will see that, for example, the first line
has a #141414 background, and the second one with the hard tabs a
#151515. It's pretty strange because there don't seem to be any
overlays or anything of this kind.

Cheers,
Jarosław Rzeszótko
