bug#15076: 24.3.50; Syntax highlighting in the octave-mode

[Ivan Oreshnikov]

Hello.

I use a color theme that assigns a different background color for
syntastic elements and I've noticed that empty space gets highlighted
with a builtin face (see screenshot in attachment). Is there a way to
fix that?
