Author: Oleh Krehel <address@hidden>
Commit: Oleh Krehel <address@hidden>

    Perform string-match in the original buffer
    
    * ivy.el (ivy--exhibit): Wrap in `with-current-buffer'
      `ivy-state-buffer'.
    (ivy-recompute-index-swiper): Reset to the candidate at the current line
    number, in case the previous regex resulted in 0 candidates.
    
    Fixes #298
