I'm not sure it needs to be documented, it is internal, after all.  I'm
using it because I want a different UI than what vc-print-log provides.
The latter passes the file name to vc-print-log-internal already
expanded; I should have checked that when I decided to use the internal
function.  But I don't see at first glance why the unexpanded file name
in the latter worked prior to the literal-pathspecs change but not
afterwards.
