As described in http://svn.haxx.se/dev/archive-2009-10/0682.shtml, if the
current working path contains a lower case drive letter, then
libsvn_subr/dirent_uri.c:svn_dirent_get_absolute() will fail if asked to find
the absolute path of a relative path with an upper case drive litter, e.g.
'C:somepath'.
Ultimately this is an APR bug in apr_filepath_merge(), which doesn't consider
the possibility of a mismatch in case for drive letters, see See
http://www.mail-archive.com/dev@apr.apache.org/msg23168.html.
rhuijben added a C-test for this issue in
