Nice, thanks for the clear info.

Yes, I learnt this from Bert last week, and also that the current *@BASE*
commandline keyword refers to the "copy_from" of the *WORKING* tree for all
the add-with-history schedules :)

BTW, is that svn_wc__db_pristine? WORKING's BASE? :P

Hadn't seen it that clear yet.

But read_info fills up the revision, repos_relpath and root_url from the
BASE tree even when a node is present in the WORKING tree, right?
(read_info's comment sounds like it:
" * The information returned comes from the BASE tree, as possibly modified
  * by the WORKING and ACTUAL trees. ")

So when read_info returns a non-"empty" revision, repos_relpath or root_url,
then these values have definitely come from the BASE tree?
Does that mean the two calls that only ask status, revision, repos_relpath
and root_url, passing NULL for all other return-parameters, are in fact
perfectly identical?
