guix-play/emacs/guix-ui-package.el
Alex Kost 6b3a1ce8d7 emacs: Fix heading face in "Package Info". 
Reported by Ludovic Courtès <ludo@gnu.org> on #guix.
This fixes a regression introduced in commit 7171d824.

'insert-text-button' procedure does not allow to override a button face,
so a specialized button type should be used instead.

* emacs/guix-ui-package.el (guix-package-heading): New button type.
  (guix-package-info-insert-heading): Use it.
