Thanks for explaining. What is the recommended way to pacify the byte 
compiler in this situation? I tried prepending (eval-when-compile 
(require 'vc)) to vc-bzr.el, but that doesn’t suffice, as the 
byte-compiler still complains “vc/vc-bzr.el:1337:1:Warning: the function 
‘vc-deduce-fileset’ might not be defined at runtime.”
