gitaliases | Bash aliases and functions for easier use of git

ITNOA

Hi,

I have a net standard project, and i want to create build script with cake for this project, I download build.ps1 from resource of cake and move it to Build directory, then create a build.cake file like below

Currently, I'm writing a PowerShell module which automatically configures aliases for all git commands, inspired by git-sh.

Then I wrote functions below.
The Enable-GitAliases function is the entry point to configure aliases automatically.
it collects git's subcommands by Get-GitCommands, which parses git --help -a to get all git's subcommands.
Then it defines the wrapper functions for the collected git commands.

My question is: why is git --help -a called so many times (possibly infinitely) when invoking Enable-GitAliases, which causing significant slow down?

After writing the code, I found Enable-GitAliases takes too much time (I've never seen it finishes).
According to the Task Manager, the git --help -a command is launched and exits repeatedly.
I expected the git --help -a command is called only once.
Actually, Get-GitCommands | % { echo $_ } calls git --help -a only once.
What is the difference, and what is best way to fix?
