Details:

This happens (only) for strings with DOS-style line ending (\r\n).
For instance, the attached test program yields the following output for the
string 'abc\r\ndef\r\n'.
0 -> start=0 end=2/5
1 -> start=0 end=2/5
2 -> start=0 end=2/5
3 -> start=0 end=2/5
4 -> start=4 end=4/5
5 -> start=5 end=7/10
6 -> start=5 end=7/10
7 -> start=5 end=7/10
8 -> start=5 end=7/10
9 -> start=9 end=9/10
The expected output (generated on OS X) is
0 -> start=0 end=3/5
1 -> start=0 end=3/5
2 -> start=0 end=3/5
3 -> start=0 end=3/5
4 -> start=0 end=3/5
5 -> start=5 end=8/10
6 -> start=5 end=8/10
7 -> start=5 end=8/10
8 -> start=5 end=8/10
9 -> start=5 end=8/10
Note that contents end is 2/7 rather than 3/8 for the first four characters of
each line and 4/9 instead of 3/8 for the last character.
