custom parentheses option with start value of greater then 2 characters

I'd love to use your plug in for VHDL. Which users mainly text instead of parentheses. I have tried to configure the plugin to do this but I have noticed that when I have "start=for" inside my parentheses option it doesn't work. Upon futher investigation it seems to be related to the number of characters it is searching for. (setting "start=fo" words, start="for" does not. Which is odd since the "step" and "end" values can be more then 2 characters and it works fine just not "start".

Please try the following setup and file. Note: "if"/"else"/"end if " will work. "for" and "end loop" will not.

my vimrc config:

        let g:rainbow_conf = {
      \    'guifgs'  : ['RoyalBlue1', 'SeaGreen3', 'Orange', 'IndianRed', 'Magenta'],
      \    'ctermfgs': ['Blue', 'Cyan', 'Green', 'Red', 'Magenta'] ,
      \    'operators': '_,_',
      \    'separately': {
      \       '*': {},
      \       'vhdl' : {'parentheses': ['start=/(/ end=/)/ fold',  'start=/^\s*if\>/ step=/\<else\>/ end=/\<end if\>/ fold', 'start=/^s*for\>/ end=/\<end loop\>/ fold']},
      \   }
      \ }
