I did some testing and xrdb seems to strip those automatically when
reading ~/.Xresources, so they never end up there. I don't have that
from any official documentation though.

I think this is actually not the case, because when I move the
remaining data to the front of the buffer, I do not move the null
char. I move only the data that is passed to the function (which might
not contain a trailing null).

I did leave this unchanged. This is better to be done by somebody who
knows what they are doing, not just guessing.

Thanks, I was not completely clear on how to do this before. I added
it to _cairo_xcb_surface_get_font_options, as that seems consistent
with the rest of the XCB code.

Thanks again for the review. Updated patch attached.
