Getting around spf13-vim's ctrlp_user_command in order to set ctrlp_custom_ignore

let g:ctrlp_custom_ignore

" The custom ignore feature in ctrlp.vim is a useful feature
" when you want to ignore files and folder in your directory
" structure. However if yo set g:ctrlp_user_command then
" g:ctrlp_custom_ignore had no effect. This is all well and
" and good unless you use a vim distribution like spf13-vim
" that just so happens to set g:ctrlp_user_command. So here
" is how you get around that issue in your own .vimrc.local:
"
" unlet the original spf13-vim settings
unlet g:ctrlp_custom_ignore
unlet g:ctrlp_user_command
" set your own custom ignore settings
let g:ctrlp_custom_ignore = {
    \ 'dir':  '\.git$\|\.hg$\|\.svn$\|bower_components$\|dist$\|node_modules$\|project_files$\|test$',
    \ 'file': '\.exe$\|\.so$\|\.dll$\|\.pyc$' }

Worked perfectly, thanks.
