Description

This updates the documentation for using forgit as a subcommand of git by removing the use of the export built-in. For all intensive purposes, PATH is already exported. If it weren't, then executing a subprocess (ex. system("bash ...")) would always fail since PATH wouldn't be copied from parent to child. This simplifies the export line accordingly.
