The git command cannot be included with
a-Shell. Would you like to create a
script at \$HOME/Documents/bin/git that
wraps lg2 with the following contents?

$(wrapper_script_contents)

Keep in mind that git and lg2 options
are not 100% compatible, and they also
do not use the same configuration files
or environment variables.
