This is a small tweak that reloads the assign's when the assigns are listed.
This can be used to copy assigns from one shell to another.
For example if you have 2 open shells, and in the first one you add a new assign. This new assign will not be available until shell 2. If you now list the assign's the new assign will become available.
Shell 1:
> assign NewAssign /home
In shell 2:
> echo $NewAssign
> assign
Assigned var's:
NewAssign=/home
> echo $NewAssign
/home
