This is another version of the well-known problem with our authn/authz
system when using "Satisfy Any". The log command sends an http REPORT
request on a (path, rev) pair. If the initial (path, rev) target is
anonymously readable, then there's no authentication ever, and the user
remains anonymous for the entire REPORT: unreadable revisions are
skipped over. If the initial (path, rev) target is unreadable, then
authentication is demanded, and that user is authenticated for the
entire REPORT.

In other words,

   1. you only get one chance to authenticate at the beginning;
authentication cannot happen in the middle of a response.

   2. your authentication lasts for the whole response.
