julianfoad_at_edith ~/src/subversion-cyan/tt
$ svn export $SVN_REPOS/trunk/www ../tt
svn: Destination directory exists; please remove the directory or use
--force to overwrite
svn: '../tt' already exists

No. It is explicitly documented as behaving differently depending on
whether you supply a directory argument. Always has been:

$ svn export --help
export: Create an unversioned copy of a tree.
usage: 1. export [-r REV] URL[@PEGREV] [PATH]
       2. export [-r REV] PATH1[@PEGREV] [PATH2]

  1. Exports a clean directory tree from the repository specified by
     URL, at revision REV if it is given, otherwise at HEAD, into
     PATH. If PATH is omitted, the last component of the URL is used
     for the local directory name.

Not, as in most other commands, "If PATH is omitted then '.' is

I agree the behaviour is surprising when you encounter it the way you
did, but it's easily understandable when you read the help.
