What is this [ -f "$dir" ] line doing?  The purpose of these
lines is:

 - The user (might have) said "clone to $2";

 - If the user didn't, then set dir to humanish part;

 - If that exists, we barf.

I do not see any valid reason for an additional logic in this
sequence when adding a new clone _source_ type.

The check to see if "$dir" _exists_ is even worse.  If the user
said "clone _to_ this", then we would not have invented $dir
based on the $repo (which is what the user said "clone _from_")
but used whatever name the user has given us.  The existing
check to barf "Hey, that explicit location you told me to clone
to is WRONG!!!" should not be broken.
