when configured both ix and ax, it need extra time to expand region

[ZSaberLv0]

1. config:

   let g:wildfire_objects = [
           \   "i'", 'i"', 'i)', 'i]', 'i}', 'it',
           \   "a'", 'a"', 'a)', 'a]', 'a}', 'at',
           \ ]

2. with this text: (| is cursor pos)

   abc('xy|z')

3. result: you need 4 times to fuel to select ('xyz'), which should be 3 times for convenient
