>+        svn-create-patch fails when svn mv is used on directory trees
>+        <https://webkit.org/b/14590>
>+
>+        Reviewed by NOBODY (OOPS!).
>+
>+        * Scripts/VCSUtils.pm: Export parseSvnDiffStartLine() for
>+        svn-create-patch.
>+        (parseDiffStartLine): Use parseSvnDiffStartLine().
>+        (parseGitDiffStartLine): Document a prerequisite.  Fix a bug
>+        when parsing git patches using --no-prefix with CFLF or LF line
>+        endings.  Found by new tests written for
>+        Scripts/webkitperl/VCSUtils_unittest/parseDiffStartLine.pl.
>+        (parseSvnDiffStartLine): Add.  Extract logic from
>+        parseDiffStartLine() for use with svn-create-patch.
>+
>+        * Scripts/svn-create-patch: Update copyright and license.
>+        (generateDiff): Return early for moved directories since
>+        individual files within the directory are handled separately.
>+        (generateFileList): Keep track of moved directories in the
>+        @additionWithHistoryDirectories array, then process this array
>+        in reverse order to create delete/add patches for each file in
>+        a moved directory.  This also prevents duplicate patches.
>+        (manufacturePatchForAdditionWithHistory): Fix a long-standing
>+        bug where the path used to describe property changes contained
>+        the original (moved-from) path instead of the new (moved-to)
>+        path. This could cause svn-apply to fail mysteriously when
>+        trying to apply an empty patch created by the property change
>+        containing the moved-from path.
>+
>+        * Scripts/webkitperl/VCSUtils_unittest/parseDiffStartLine.pl: Add.
>+        Tests for parseDiffStartLine(), parseGitDiffStartLine() and
>+        parseSvnDiffStartLine().
