I noticed that when I create a nvm function, as suggested in the readme, it reverts the currently used node version (from an .nvmrc file)

ie,

In .config/fish/functions/nvm.fish

function nvm
    bass source ~/.nvm/nvm.sh ';' nvm $argv
end

In a directory where I have a .nvmrc file with iojs-v2.2.1 and I run

$ nvm use
Found /Users/ttt/Work/Dev/folder/.nvmrc with version <iojs-v2.2.1>
Now using io.js v2.2.1
$ which node
/Users/ttt/.nvm/versions/io.js/v2.2.1/bin/node

which is good. But then when I run nvm current:

$ nvm current
v4.1.1
$ which node
/Users/ttt/.nvm/versions/node/v4.1.1/bin/node

It reverts back to my default version, which in this case is v4.1.1. Same for other functions that read the status of nvm eg, nvm list

Is there a way to run current or other ready only functions without loading the default?
