    I believe I stepped through at one point and found that it was getting set 
    to nil when erase-buffer was called.

It seems strange that erase-buffer clears buffer-file-coding-system.
Looking at the code of Ferase_buffer, where could it do that?

Can someone please try stepping thru Ferase_buffer and its
subroutines, and see how it happens?
