I got so involved in the problem of mapping <CR> that I forgot about
mapping /. Here's a better example, again just fleshed out to the
point of working, but closer to a complete solution.
:nnoremap / :call SlashEscape()<CR>/
:function SlashEscape()
: cnoremap <CR> <C-\>eescape(getcmdline(), '/')<CR><CR>:cunmap
<lt>CR><CR>
:endfunction
