Subject: Enable recursive swiper calls
X-Git-Url: https://code.delx.au/gnu-emacs-elpa/commitdiff_plain/c546ae47503b3dfa76bebaa461ce6febe700f753

Enable recursive swiper calls

* ivy.el (ivy-read): Don't need to be in the minibuffer to do a
  recursive store/restore.

(ivy--reset-state): Avoid nil string while testing.

Fixes #309
