I'll make a patch for svn_dirent_is_absolute and send it to the list, I will only need it later when adapting the path functions to dirent/uri.

It was 3:40AM when I wrote that mail, no wonder you don't see it ;)

What I'm saying is this: an absolute path = current working directory +
a relative path. So suppose I do this:
c:\svn\wc\> svn diff test.txt

In this example Subversion can get the full path of test.txt by
concatenating 'c:\svn\wc\' and 'test.txt'. I don't know if 'svn diff'
actually uses the absolute path, but this is basically what
svn_path_join does.

Now take this example:
c:\svn\wc\> svn diff G:test.txt

If 'G:test.txt' would be considered a relative path, then Subversion
would think 'c:\svn\wc\G:test.txt' is the absolute path for test.txt,
which clearly is incorrect. So for practical reasons we consider
'G:test.txt' as an absolute path, but you're right in saying
conceptually it's actually relative.
