    Fix parsing error for numbers with leading space
    
    * src/style.c(trim_space) : ensure right being bigger than left
    (sp_style_merge_from_style_string) : use it to get the right length
    for values with leading spaces; before they contained the trailing
    ';' and thus were not interpreted correctly
