Move vim option select to execute logic at alias def time

Using the function would cause problems when trying to perform a `sudo
vim`. The sudo command would run in a root shell which does not have my
shells functions (but does have it's aliases) so then any attempt to
sudo vim would fail with "vim_option_select: command not found"
