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.
