cmder/vendor/profile.ps1
Jackbennett db909451c9 Version Check the Posh-Git module to allow module autoloading
Posh-Git before this release does not export `Write-VcsStatus` thus
powershell's autoloading cannot find the reqired module for the function.

note that `get-module -listAvailable` can return an array of multiple
versions.
