    unicode: Fix a few issues with G_UNICHAR_MAX_DECOMPOSITION_LENGTH
    
    Raised by Matthias in bgo#665685 but which I didn't spot until after pushing
    commit 3ac7c35656649b1d1fcf2ccaa670b854809d4cd8.
    
    Renames G_UNICHAR_MAX_DECOMPOSITION_LEN to G_UNICHAR_MAX_DECOMPOSITION_LENGTH
    and fixes a few documentation issues.
    
    See: bgo#665685
