That is a somewhat puzzling pattern. It matches *, optional  
whitespace, a sequence of ‘not * or space’ or the ‘.’ character, or  
the ‘ * ’ sequence. And then finally a ‘*’.

The second branch is redundant and the third I think is unwanted.

What it can’t identify is when the terminating ‘*’ has spaces on both  
sides, as it will then be taken by your middle repeat, and the  
terminating state is never met.

Well, not entirely sure what you want to match, but sounds like just:


That matches from asterisk to asterisk.
