What happens to blank lines?
When 'Delete blank lines' is enabled, blank lines are removed before joining. Otherwise, they produce empty segments in the output.
Is this the inverse of Split Text?
Yes. If you split by comma and then join by comma, you get back the original text (minus blank lines and trailing spaces if those options are enabled).
