I guess you're right, I've moved it further down. There is in fact a
message about the xlog location (unless you switch off wal entirely),
but having another one right before that mentioning the completed
checkpoint sounds ok to me.

There's also some inconsistencies around which messages are prepended
with "pg_basebackup: " and which are translatable; I guess all messages
printed on --verbose should be translatable? Also, as almost all
messages have a "pg_basebackup: " prefix, I've added it to the rest.
