Not sure about my previous patches 0004 and 0005.  IMHO that commit 
d494833d47968fcd97ba549654a259d6fb6c2eee which introduced all these 
issues looks a bit flaky.  (It does not even have a NEWS entry!)

I think I understand what it's doing and the intention seems noble, even 
if it covers only a subset of VC operations.  But that 
`with-current-buffer' around `vc-deduce-fileset', where that function 
explicitly declares that it changes buffer, seems to ask for more trouble.

Probably somebody with deeper VC insight should review both commit 
d494833d47968fcd97ba549654a259d6fb6c2eee and my patches.
