Can we pause for a moment?
As I mentioned to you earlier, you should post such patches for review
before installing them.
And explain why you think they're good.
E.g. replacing buffer->overlays_before by "buffer_get_overlays (buffer,
OV_BEFORE)" is far from "obviously good" in my eyes.
If you intend to make those field accesses into something more complex,
then please say so and explain why. If not, then please stick to
"foo->bar", as agreed for the FGET case.
Stefan
