If the first argument to just contains a `/`, then it will be handled
specially. Everything before the last `/` is treated as a directory, and
just will search for the justfile starting there, instead of in the
current directory.
Previously, only one recipe with parameters could be passed on the
command line. This was to avoid confusion in case the number of
parameters a recipe took changed, and wound up using as an argument was
was once a recipe.
However, I don't think this is actually particularly confusing in
practice, and could be a slightly annoying limitation.
Now, any number of recipes with parameters may be given on the command
line.

Recipes may now have a final variadic parameter:
```make
foo bar+:
@echo {{bar}}
```
Variadic parameters accept one or more arguments, and expand to a string containing those arguments separated by spaces:
```sh
$ just foo a b c d e
a b c d e
```
I elected to accept one or more arguments instead of zero or more arguments since unexpectedly empty arguments can sometimes be dangerous.
```make
clean dir:
rm -rf {{dir}}/bin
```
If `dir` is empty in the above recipe, you'll delete `/bin`, which is probably not what was intended.
Looks like this:
```make
recipe argument default-argument='default value':
echo argument is {{argument}}
echo default-argument is {{default-argument}}
```
Thanks @deckarep for the feature request!
