Well, this reads as if "blocks of 3 lines" are excluded, but what I
mean is "if all adjacent blocks combined are 3 lines or fewer"
Example of how I understand the code:
context
+ moved line, block A
+ moved line, block A
+ moved line, block B
+ moved line, block A
+ moved line, block A
context
These five lines are colored, because 5>3, but each
individual block is smaller than 3 lines. However we
already want to tell the reviewer that the middle line is not part of
a contiguous 5 line block, so we have to use alternative color
in the middle.
However
context
+ moved line, block A or B
+ moved line, block A or B
context
is omitted, because the number of lines
here is fewer than 3 ignoring the block
type.
Maybe
If there are fewer than 3 adjacent lines of
moved code, they are skipped.
Thanks,
Stefan
