Subject: [PATCH] org-num: Fix bug in check for commented headlines
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* lisp/org-num.el (org-num--skip-value): Handle empty headlines.

This happens when org-num-skip-commented is non-nil.  When creating
a new headline, often org-num--skip-value is invoked before any
headline text is created. This means that ‘title‘ is nil and the
string-match check breaks. Checking if title is non-nil fixes this.
