Powershell path parsing problem (Windows)

[raphaelreyna]

When the -s flag is used to pass in a shell to use, oneshot parses the path as having double slashes. This then leads to a 'file not found' error.

example: C:\Windows\System32\WindowsPowerShell\v1\powershell.exe -> C:\Windows\System32\WindowsPowerShell\v1\powershell.exe

This was somewhat resolved by making PowerShell the default shell on Windows.
