1. Because the algorithm finds all possible matches, the greedy or ungreedy
nature of repetition quantifiers is not relevant (though it may affect
auto-possessification, as just described). During matching, greedy and ungreedy
quantifiers are treated in exactly the same way. However, possessive
quantifiers can make a difference when what follows could also match what is
quantified, for example in a pattern like this:
<pre>
  ^a++\w!
</pre>
This pattern matches "aaab!" but not "aaa!", w
