Tabbing while starting command with '(' causes exceptions

[Hideki Ikeda]

NOTE to admin: If this is not the place to post bugs, please delete this post

While in Pash console, type '(Get-Hos' and then hit the <tab> key for completion (intention was to call '(Get-Host).CurrentCulture' for example)

Result:

System.ArgumentException: parsing "^(Get-Hos.*$" - Not enough )'s.                                                      

Parameter name: ^(Get-Hos.*$

Target platform: Ubuntu 14.04.1 (x86_64)

I'd like to help debug this, but I do not have time to look until next week...
