Agreed. Was thinking exactly the same thing.

I wonder, though: isn't this rev-range support better situated in the RA
layer itself, extended up to the server? I ask because IIRC, the fallback
implementation of svn_ra_get_repos_locations() uses none other than the
'log' functionality.

So I see this:

  BEST CASE: client's RA layer and server can handle log-with-ranges

  FALLBACK 1: client RA layer works around server's lack of log-with-ranges
      support by using get_locations() and a series of log requests

  FALLBACK 2: client RA layer works around server's lack of log-with-ranges
      support and lack of get_locations support by using a single
      log request from which disinteresting revisions are merely filtered
