Hi List,
I face the problem that I set a buffer-local variable in one function,
and find its value to be nil later on in another function. In between,
'revert-buffer' is called with a revert-buffer-function that uses
erase-buffer.
I experimented a bit, and during the experiments it seemed that
'erase-buffer' doesn't modify buffer-local vars. But then I don't really
understand how its possible to set a variable (even print out its value
in a message call) in one function, but find its value to be nil again
later on without touching it explicitly in between.
Any hints would be welcome.

cheers,

Following up to my own post:
I figured out that its not 'erase-buffer' that is the culprit, but a
temporary change of major-mode, because by convention:
