Add support for implicit $@

Fixes #29

You might want to add tests for this one 🚀

Hi @Neved4!
I believe we don't want to quote $argv in the resulting fish code. For example, when executing the following script with the arguments 1 2 3 we get a number per line.

for cmd; do
  echo "${cmd}"
done

The fish snippet:

for cmd in "$argv"
  echo "$cmd"
end

Will put all numbers in a single line because it only runs once (it converts the argument list into a single string).

Thx a lot @JoaoCostaIFG, you're 100% right!

Just pushed another commit, cheers.

Would also appreciate any guidance for tests on this one!

Cool, please add some tests indeed. Adding a test that has the examples in your issue would be a good start

[Neved4]

Added!
