I remember something of the same, but I don't think it was on this list 
-- perhaps one of the earlier cl-emacs efforts?

I think it's safe to remove the syntax reset (ie. the setf on the 
buffer's syntax slot) in com-switch-to-buffer (and com-find-file, FWIW) 
-- even if you're switching to a new buffer (should a fresh buffer 
really be created?) (or finding a new file) a buffer is initialised with 
a fresh basic-syntax by an :after method on initialize-instance in 
pane.lisp.

Which is a convoluted way of saying: since it's already impossible to 
have a buffer without a syntax, the only command which should touch the 
syntax is Set Syntax (at the moment); Switch To Buffer and Find File 
should leave it alone.
