Selectively enable `delimitMate_expand_cr`?

[demon386]

Hi, I want to be able to enable "delimitMate_expand_cr" only for curly braces {} but not parentheses (), while keeping other functions the same for the two.

Is this possible?

Similarly, I wanted to enable it for >:< so HTML tags are automatically expanded when I press Return inside an empty tag. But of course I didn't want to have the other delimitMate features for the >:< pair.

I hacked the following together:

imap <silent> <expr> <CR> <SID>delimitMateCR()
imap <silent> <expr> <BS> <SID>delimitMateBS()
imap <silent> <expr> <C-h> <SID>delimitMateBS()

function! s:delimitMateCR()
  call s:temporary_matchpairs()
  return "\<Plug>delimitMateCR"
endfunction

function! s:delimitMateBS()
  call s:temporary_matchpairs()
  return "\<Plug>delimitMateBS"
endfunction

" Hack: Temporarily change delimitMate_matchpairs to make delimitMateCR and
" delimitMateBS work with more characters
function! s:temporary_matchpairs()
  if exists('s:matchpairs_timer')
    call timer_stop(s:matchpairs_timer)
  endif
  if !exists('b:delimitMate_matchpairs')
    let b:delimitMate_matchpairs = g:delimitMate_matchpairs . ',>:<'
    silent DelimitMateReload
  endif
  let s:matchpairs_timer = timer_start(100, {-> execute(['unlet! b:delimitMate_matchpairs', 'DelimitMateReload'])})
endfunction

This temporarily adds >:< to b:delimitMate_matchpairs when you press Return or Backspace.

Although this works, it would be nice if delimitMate had an option to specify the characters for delimitMateCR and delimitMateBS.
