Line wrapping was removed from the latest version of the syntax highlighter library that we're using, as it was causing formatting problems for some copy and paste instances, but I'll see what we can do about improving the highlighting for powershell.

previously, using the sourcecode block like this:

[sourcecode language="PowerShell"]

[/sourcecode]

would wrap my code text - now it just runs off the right side of the page and hides under my right-column of stuff (tags, categories, etc). . .

also, the syntax highlighting of powershell isn't very helpful - it would be great if it would show syntax highlighting just like the PowerShell Integrated Scripting Environment (ISE)
