Most of the time people use `*alias*` to wrap another command with some
predefined options. And you normally want to allow the user to augment
those with additional arguments. For example I have this alias:
alias h 'builtin history search -R -20 --show-time="%a %m-%d %R "'
If I type `*h git*` I want to search for commands containing the word `*git*`.
It would also be quite surprising to define an alias that silently ignored
any arguments it was invoked with. If you do want a function that should
never be run with any arguments you should do so explicitly:
function greet
if set -q argv[1]
echo greet: no arguments allowed >&2
exit 1
end
echo Hello $USER
end
