@dscho reached out to me about bundling posh-git with Git for Windows, which I certainly support.

My tentative suggestion would be to have the Git for Windows installer detect a supported PowerShell version (see dahlbyk/posh-git#328 for version support discussion). If available, launch PowerShell to execute a script that runs Install-Module (included in 5.0+, or via PackageManagement PowerShell Modules Preview, if available.

Do you have any way to install it system-wide? (Git for Windows installs system-wide, therefore installing posh-git for the installing user would be a little unfortunate.)

Install-Module accepts a -Scope parameter of either CurrentUser or AllUsers (paths). I assume the Git for Windows installer would be able to spawn an elevated shell to install with AllUsers.

The other part of installation is to inject Import-Module posh-git into a PowerShell profile, which can be one of:

1. Current User, Current (Default) Host
2. Current User, All Hosts
3. All Users, Current (Default) Host
4. All Users, All Hosts

posh-git's Add-PoshGitToProfile supports -AllHosts but does not support toggling CurrentUser/AllUsers.

Also: what's your release cadence? Would you like to coordinate with Git for Windows releases, or are you fine with me simply picking up the latest posh-git whenever I see a new one?

Release cadence is....infrequent? I'd just let PowerShellGet install the latest for the given platform.
