Here is that patch.

I understand that some people are queasy about using advice in code like this, 
and am open to suggestions about alternatives.
What the code needs is a reasonable (not necessarily bullet-proof) way to 
detect new file buffers and changes to buffer-file-name of those buffers. 
Monitoring `find-file-noselect' and `set-visited-file-name' turned out to be 
good enough.
For the former, it might be possible to get away with 
`after-change-major-mode-hook' instead (already used for non-file buffers).
