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

["Jarosław Rzeszótko" <sztywny@gmail.com>]

Hi,

I reproduced it now with Emacs 24.3.50.1. It's the same with emacs -Q,
it does not change when changing the gtk+ theme, the one external
thing I thought might maybe influence this. I am just running a new
emacs session, using customize-face on the "default" face, setting
background to #151515, foreground to #ffffff, and opening a file where
some lines are empty and some lines have a bunch of tabs (I mean the
"hard" tab character, not just a bunch of spaces) and some text in
them. The difference is background might not be easily noticable but
it is there. It's similar for other dark background, the tabs+text
lines get different background than empty lines.

Cheers,
Jarosław Rzeszótko
