When I press <CR> in REPL (same thing with <C-Up> and <C-Down>, but, strangely, not with <C-CR>), the text
is inserted into REPL instead of submitting a command. <C-CR> works fine (it submits the command).
Hat (^) does not seem to have any effect at all.
I have VimClojure v2.3.3 installed, Vim 7.3.600, Archlinux. Tested in GVim and terminal vim.
