Create a decent question title based on taxonomy and question body.

This is themeable so others can create their own titles without too much trouble: 1. Pick the first taxonomy term from the first vocabulary. 2. Append a numeric sequence. 3. Append the first 50 chars of question body, or less, depending on where the word breaks are.

Parameters

$node: The question node to generate a title for.

Return value

A title string.
