Calling opendir(3) on a plain file is using "the correct API".
So is calling svn_ra_get_file on a directory. Try-and-fail is
better than test-first, but I'm not going to argue that here.
So, here is what I'm doing:

- I have a path which may be a file or a directory
- I need to get its properties and contents if it's a file, or
  just its properties if it's a dir
- Most paths are files
=> try:
   except NOT_FILE:

It's just more complicated than it needs to be because I also
have to support DAV.

That's the story of my life right there: "It's harder than it
should be because of DAV."

So, in most cases (files), I issue one get_file and am done; in
the (rare) case of a modified directory, I issue two requests:
get_file and get_dir2. Issuing a check_path on every single path
just to find this rare case would be stupid[1].

Well, that's where we (gvn) are for other reasons anyway, as
we've discussed on IRC.

[1] Note that svn does this all the time, sigh. Check out what
    we do for 'svn cat':

      reparent /welcome
      check-path /welcome_at_119767
      get-file /welcome r119767 props
      get-file /welcome r119767 text

    All I should see in the log for svn cat is this:

      get-file /welcome r119767 text props

    Sure, svn cat, who cares? I wonder how many other places we
    have crazy things like this...
