FWIW, I tested with mercurial (vc-hg.el) and it works correctly (as with
git) but it have the same call to 'vc-setup-buffer' in
'vc-hg-print-log'.  So I guess it would be logical that others backend
"print-log" functions have this same call.

(note: I could not test it but SVN and Bazaar print-log functions also
have this call to 'vc-setup-buffer')
