docs command doesn't work properly with numbered args

[Cody Allen]

Doing something like docs 3 where 3 is a numbered argument from a previous find command doesn't work. I think that it used to and that this is a regression. The error message shows a trailing hash and if you issue the same docs command with the hash removed, it works fine.

This might have been a regression with the recent completion/fzf overhaul?

Sadly this has never worked and I reported an issue for it here #3939
