Don't autocomplete already supplied arguments

[nagisa]

There's two files in current working directory:

• [f] a.png
• [f] b.png

When writting command

rm [f\]\ a.png [f\]\ b.png

I can resort to autocompletions to write command faster.

So instead of writing whole name I can press [ and then →, however when writing second filename it again suggests [f]\ a.png, which is already to be removed. I have to resort to Tab then writing b and pressing Tab again which could be avoided if fish didn't autocomplete filenames that were already supplied.

EDIT: Same with
