Missing notes for new IEnumerable<string> methods
I noticed is that the documentation for some of [new IEnumerable methods in System.IO I wrote before] is missing important parts. For example, the [old method] has notes about [unstable sorting] and about the different behavior for patterns where the extension is exactly three characters long. But the [new one] is missing these notes and these are quite important, in my opinion. I hope this is just because we're in RC stage and in RTM all will be ready. Else it could cause confusion when using new methods (until you find the string version (or this post ;))).
