Subject: [PATCH] Fix the uncaught exception when doing opening a link from
 nowhere

* lisp/org.el (org-open-at-point): Make sure point is on a
org-plain-link-re before trying to go to its beginning

In cases the custor at point did not match anything, the piece of
code (goto-char (car (org-in-regexp org-plain-link-re))) threw an
error.

The inital intention of avoiding matching a org-plain-link-re when
just after a org-bracket-link-regexp, from the commit originating
the error (ad35e2ac6c6decae55dd987be738e07e7c87bd7d) was conserved.
