    Fix bug #8891 (wrong depth of copied text)
    
    This was an obvious thinko: When pasting a paragraph list the depth of the
    pasted paragraphs need to be adjusted, so that no paragraph has a negative
    depth afterwards. However, the maximum allowed depth was only adjusted after
    the second and following pasted paragraphs. Since the computed value was 
only
    used for the subsequent paragrph this meant that the second paragraph did
    still use the same maximum allowed depth as the first one, which came from 
the
    paragraph the text as pasted into. This was wrong e.g. in case the outside
    paragraph was a standard paragraph (max_depth = 0), and the first pasted
    paragraph was an enumeration (max_depth = 1). Therefore, max_depth needs to
    be adjusted also after the first pasted paragaph. Since the adjustment is
    done aftre max_depth was used for the current paragraph the condition
    mentioned in the comment is still met.
