In the home directory there is a .terraform folder for modules but it is most likely not
an actual directory of terraform scripts. Therefore, this patch disables checking for workspace in the home directory.
* Fix the terraform function name
Current function name do worse. I always use `terr<TAB>` and before those prompt it was add space in the end. Now because we have multiple functions and binaries started with terraform there are no space.
* Updated terraform readme
Updated the name of new function name
