        - fixed <rdar://problem/4025918> images copied from Safari with relative src URLs aren't pasted into Mail messages (KURL resolves base URLs incorrectly)

        * kwq/KWQKURL.mm: (KURL::KURL): Add a slash at the start of the path if a relative part is adding
        a path onto a URL that has "pre-path" bits like host name, but no path yet. This doesn't come up
        for http because in that case we add a trailing "/" as part of canonicalization.
