Issue Description

Reindent Lines breaks here-strings

After running Reindent Lines:

function get-test 
{
        write-host @"
        something    
        "@
}

This breaks there here-string as white space is not allowed before the string terminator (which the syntax highlighter correctly points out). Also you do not usually want additional white space added in the middle of a literal string. Possibly related to #961

Looks like there is one open already. https://github.com/PowerShell/PowerShell/issues/2337#issue-178501482

@Eisen-Hardt the ability for "@ to have spaces/tabs in front of it would actually be a PowerShell feature.

Can you open an issue here?

Today, a script wont work properly with anything in front of the closing here string ("@)
