Subject: Log org export errors to package-vc doc buffer
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=335631506dc68b28a156ad0e8b31ae479ae7b851;p=emacs.git

Log org export errors to package-vc doc buffer

* lisp/emacs-lisp/package-vc.el (package-vc--build-documentation):
Wrap the org-export logic in condition-case, allowing package
installation to continue while preserving error messages.  (Bug#65649)
