Thanks!

Thanks. It seems only natural that we try and fork the repo we're in as a default, good catch.

There is some logic that need to change, though. The rest of the script assumes that it should clone the repo, cd into it and add the argument (here $url) as a remote called 'upstream'. See this part

What we want to do in this case is just rename origin to upstream, and add the fork as origin.

The man pages also have to be updated to reflect that we will have a default value, and that git fork will do as I just described when ran without arguments.

A little quick on the trigger there, @hemanth ;)

@npcode We'd appreciate a new PR with the changes I suggested. Please comment if anything was unclear, or if someone has other suggestions.
