You want to edit the buffer so that when you 'apply' the resulting
changed buffer, emacs reflects those changes in the original files.

See eg wgrep:

    ## Summary:

    wgrep allows you to edit a grep buffer and apply those changes to
    the file buffer like `sed` interactively. No need to learn sed
    script, just learn Emacs.
