pg_rewind: Should abort if both --source-pgdata and --source-server are specified

Hi, ISTM that pg_rewind's --source-pgdata and --source-server options are mutually exclusive, and the synopsis in the documentation seems to indicate that as well: |pg_rewind [option...] {-D | --target-pgdata} directory |{--source-pgdata=directory | --source-server=connstr} However, there is no such check in the code. I've seen people assume --source-pgdata is supposed to be the data directory location on the remote server if they specify --source-server as well, and are then confused by error messages. So I think pg_rewind should abort in this case. Patch for that attached. Thoughts?
