You can add a line to your .zshrc to ignore auto-correct for all git commands:
alias git='nocorrect git'
The other option is to re-create your aliases from .gitconfig in .zshrc like so:
alias 'glg'='git lg'
Note: You must have msysgit installed on your machine. Also, the path to my git install is “C:\Program Files (x86)\Git” yours might be different. Please check were yours is before continuing.
