[PATCH] Fix bug in org-num check for commented headlines

[Anders Johansson]

I found an easily solved bug in org-num.

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.
