+This configuration should prevent linebreaks and collapsed spaces for escaped LaTeX commands 
+inside listings. It assumes that listings-init contains TeX4ht specials that disables and enables spaces,
+and OutputBox and PostOutput hooks provided by Listings should insert markup for the current text color.

 Use the TextStyle hook to insert markup for inline listings. This hook can 
 be used also in other contexts, so we need to execute it conditionally, 
 based on the \Verb|\lst at ifmode| condition.
