I've seen a couple of problems in the current pretest which
disappeared once I turned off the cache in the Rmail buffer. I've
tried to see what does Rmail do that triggers this, but came up
empty-handed. Help is welcome.
In general, each insertion and each deletion in any buffer must call
invalidate_buffer_caches. I tried to find any code that doesn't, but
couldn't find anything.
Another possibility is that the tricky optimizations in find_newline
have some subtle bug, so close scrutiny of that code might find the
cause.
