Hi Brian,

Control characters in pathnames are not actually supported.

For a long time the server didn't enforce this, though, only the SVN client did.
Since server-side enforcement was lacking it was possible to add such paths with
alternative client implenentations such as SVNKit (used in the Eclipse IDE).

Current 1.8.x servers will not accept new paths containing newline characters.
See http://subversion.tigris.org/issues/show_bug.cgi?id=4340 for why.

1.9 and later servers will take this a step further and start refusing
commits which add paths containing any control character, just like
svn clients have been refusing for a long time (since 1.0 I believe):

$ touch `printf 'bb\aell'`
$ svn add bb^Gell
svn: E160005: Invalid control character '0x07' in path '/tmp/svn-sandbox/trunk/bb\007el
