Issue Description

The closing doublequote-@ ("@) in the following code is not interpeted as a closing tag:

$DesktopIniContent = @"
[.ShellClassInfo]
CLSID2={0AFACED1-E828-11D1-9187-B532F1E9575D}
Flags=2
ConfirmFileOp=1
"@

Everything after the close tag is interpreted as if it is still within the opening doublequote.

Do you have the closing tag -->
"@
typed starting at column 1? If there is a tab or space in front of it, I get that behavior, but otherwise it works. This was true with ISE also.

[ExchangeTips]

No, I didn't. Thanks. That fixed it.

[ExchangeTips]

Well, not exactly "fixed", but good enough for now.
