    [libmenu] Fix miscalulation for inlining when inline_header = true
    
    When inline_header = true for a subdirectory, the length of the content
    of the parent directory was miscomputed: instead of adding the length of
    the subdirectory, it was just replacing the current length with the
    length of the subdirectory.
    
    Also fix a typo in a comment
