[O] [PATCH] org.el: fix org--get-outline-path-1


From: Tobias Getzner
Subject: [O] [PATCH] org.el: fix org--get-outline-path-1
Date: Mon, 29 Feb 2016 15:35:28 +0100

Headline titles may be empty, in which case the respective match group
will be nil. This would throw an error when trying to regexp-replace
checkbox cookies.

TODO: Depending on preference, a place-holder string might be a better
choice (for user-display) rather than leaving the outline-path element empty.
