The following syntaxes work for me:

% SVN_EDITOR="'$HOME/pre fix/bin/vim' +%d" $svn mkdir file:///tmp/svn/r1/foo3
% $svn mkdir file:///tmp/svn/r1/foo3 --editor-cmd "'$HOME/pre fix/bin/vim' +%d"

(the +%d is there both to prove to myself that it's not simply falling
back to my default editor --- which is also vim --- and to show that
passing argv[1] to the editor works)

Why is basename(1) invoked here?

(That's almost certainly something in your configuration.)

Morale: don't use paths with spaces.
