Fix crash that occurs with empty headers with trailing whitespace when using TOC or header ids #12

Closed jasharpe closed 9 years ago

Fix crash that occurs with empty headers with trailing whitespace when using TOC or header ids. Defence in depth: handle NULLs properly in toc_header and rndr_header, but also change is_atxheader logic so that a header consisting only of whitespace isn't considered a header. This should prevent the header callback from ever being called with NULL content.

It was fixed processing of empty header. Please check.
