* helm

  Evil bindings for [[https://emacs-helm.github.io/helm/][helm]].

  =M-= modifiers are preferred over =C-= so the help prefix (=C-h=) is left
  alone. =h= and =l= are reserved for minibuffer editing in =helm-find-files=
  and =helm-read-file-map=.

** Notes

   - =helm-minibuffer-history-key= is set to =M-p= via =custom-set-variables=.
   - =helm-default-prompt-display-function= is set so the evil cursor renders
     correctly in helm's header line when =helm-echo-input-in-header-line= is
     non-nil.
   - =evil-collection-helm-hide-minibuffer-maybe= is added to
     =helm-minibuffer-set-up-hook= to hide the minibuffer cursor in that case.
