[O] Bug: links are not highlighted anymore with Org Mode 9.2

[Daniel Borchmann]

Hey,

links in Org Mode 9.2 are not highlighted anymore if no :face keyword is
given in ‘org-link-parameters’.  The reason for this seems to be that
‘org-activate-links’ uses the following code to determine which face to
use:

--8<---------------cut here---------------start------------->8---
(pcase (org-link-get-parameter type :face)
  ((and (pred functionp) face) (funcall face path))
  ((and (pred facep) face) face)
  ((and (pred consp) face) face) ;anonymous
  (_ 'org-link))
--8<---------------cut here---------------end--------------->8---

However, ‘nil’ is a valid face, and thus this form returns ‘nil’ instead
of the default ‘org-link’ face if no :face keyword is given.

Best,

  Daniel

PS: Thanks a ton for Org Mode, I literally couldn’t live without it! :)
