    We search for runs as follows.  "b" marks the beginning of unwritten
    data, and "a" anchors the beginning of a run which continues to just
    before "c".   The  run length  is  "c"-"a".  Since  the  run  length
    encoding carries a penalty of additional output equal to the  length
    of the  run  length  prefix (!<number>), short runs are not encoded.

    If a long  enough run  is found,  then the  string "b"  .. "a"-1  is
    output since its length is now  known, followed by the run  encoding
    for the character at "a".  Then "a" and "b" are advanced to "c", and
    the scan continues.

    If the  run  beginning at  "a"  is too  short,  then "a"  is  simply
    advanced.

    We do not store a termination marker, but instead  keep  a  counter,
    "left", which is  decremented to  0 when the  end of  the string  is
    reached.
