Description:
------------
svn_log function with default flags (SVN_DISCOVER_CHANGED_PATHS | SVN_STOP_ON_COPY) would not provide me with path changes.

Forcing the flags parameter to SVN_DISCOVER_CHANGED_PATHS wouldn't either.


Reproduce code:
---------------
define( 'SVN_USER_NAME', 'user' );
define( 'SVN_PASSWORD', '' );
define( 'SVN_PROTOCOL', 'svn' );
define( 'SVN_HOST', '127.0.0.1' );
define( 'SVN_REPOSITORY', 'repos/' );

svn_auth_set_parameter( SVN_AUTH_PARAM_DEFAULT_USERNAME, SVN_USER_NAME );
svn_auth_set_parameter( SVN_AUTH_PARAM_DEFAULT_PASSWORD, SVN_PASSWORD );

$url_repository = SVN_PROTOCOL .'://' . SVN_HOST . '/' . SVN_REPOSITORY;

$revisions = svn_log( $url_repository, SVN_REVISION_HEAD, SVN_REVISION_INITIAL, 0 );

echo '<pre>revisions', print_r( $revisions, TRUE ), '</pre>';

Expected result:
----------------
[0] => Array, ordered most recent (highest) revision first
(
    [rev] => integer revision number
    [author] => string author name
    [msg] => string log message
    [date] => string date formatted per ISO 8601, i.e. date('c')
    [paths] => Array, describing changed files
        (
            [0] => Array
                (
                    [action] => string letter signifying change
                    [path] =>  absolute repository path of changed file
                )
            [1] => ...
        )
)

Actual result:
--------------
[0] => Array, ordered most recent (highest) revision first
(
    [rev] => integer revision number
    [author] => string author name
    [msg] => string log message
    [date] => string date formatted per ISO 8601, i.e. date('c')
)
