    Description

      See reps-strings.c, in particular rep_read_range() and window_handler().
      
      The current undeltification algorithm is wasteful because it may spend
      time and space reconstructing data that will not end up being used. A
      real delta combiner would "compose" delta windows instruction by instruction
      and not bother with irrelevant parts; also, certain spurious re-copying of
      data would be avoided.
      
      This change is probably necessary to handle large files well; we're writing
      some fs tests to measure this more precisely.
