Feature request: Pair spaces if between brackets

[greduan]

@kana The auto-pairs plugin of the same sort as this one offers the following functionality:

Insert spaces before closing characters, only for [], (), {}

input: {|} (press <SPACE> at |)
output: { | }

input: {|} (press <SPACE>foo} at |)
output: { foo }|

input: '|' (press <SPACE> at |)
output: ' |'

From what I could observe this plugin does not have this functionality. Would be nice to have it, although this is more of an edge case and something you don't have to worry about if it's too much trouble. :)

Thank you! :)

Oh, I know how to realize it:

  if get(g:, 'smartinput_break_undo', 0) || v:version < 800
    let left = '<Left>'
    let right = '<Right>'
  else
    let left = '<C-G>U<Left>'
    let right = '<C-G>U<Right>'
  endif

  call smartinput#map_to_trigger('i', '<Space>', '<Space>', '<Space>')
  call smartinput#define_rule({
        \ 'at': '(\%#)',
        \ 'char': '<Space>',
        \ 'input': '<Space><Space>' . left,
        \ })
  call smartinput#define_rule({
        \ 'at': '\[\%#]',
        \ 'char': '<Space>',
        \ 'input': '<Space><Space>' . left,
        \ })
  call smartinput#define_rule({
        \ 'at': '{\%#}',
        \ 'char': '<Space>',
        \ 'input': '<Space><Space>' . left,
        \ })
  call smartinput#define_rule({
        \ 'at': '( \%# )',
        \ 'char': '<BS>',
        \ 'input': '<BS><Del>',
        \ })
  call smartinput#define_rule({
        \ 'at': '\[ \%# ]',
        \ 'char': '<BS>',
        \ 'input': '<BS><Del>',
        \ })
  call smartinput#define_rule({
        \ 'at': '{ \%# }',
        \ 'char': '<BS>',
        \ 'input': '<BS><Del>',
        \ })

If @kana welcomes a PR, maybe I can provide one.
