mergecopies: rename 'ca' to 'base'
This variable was named after the common ancestor. It is actually the merge
base that might differ from the common ancestor in the graft case. We rename the
variable before a larger refactoring to clarify the situation. Similar rename
was also applied to 'checkcopies' in a prior changeset.

copies: move variable document from checkcopies to mergecopies
It appears that 'mergecopies' is the function consuming these data so we move
the documentation there.
