bug#16433: 24.3.50; find_newline screws up in Rmail buffers

[Richard Stallman]

mail-fetch-field gave the wrong result for the X-RMAIL-ATTRIBUTES
field, perhaps because it happened to be last.  It included the
newline after that field in the return value, which is wrong.
Setting cache-long-scans to nil in the Rmail buffer made the
bug go away, so I think the problem is in the newline cache.

I think it would be better to fix the underlying bug, rather than turn
off the cache in Rmail mode.  I suspect that the cache does not handle
Rmail's changes in narrowing.  However, I'm not prepared to debug it
all the way myself.
