    Bug 745126 - gimp_preview_area_blend() fails for RGBA image...
    
    ...if buf1 and buf2 have same alpha value
    
    Fix a misplaced } that was causing the final write to the destination
    buffer to be executed only for the case where the alphas are
    different. Thanks to Jonathan Tait.
