Did you followed the "See also −−find−copies−harder."?

For performance reasons, by default, `-C` option finds copies only
if the original file of the copy was modified in the same
changeset. This flag makes the command
inspect unmodified files as candidates for the source of
copy. This is a very expensive operation for large
projects, so use it with caution. Giving more than one
`-C` option has the same effect.Show 8 quoted lines
