Subject: [PATCH] [Fix] make `nvm use` display `.nvmrc`'s version in output
 messages

Set $PROVIDED_VERSION equals to $NVM_RC_VERSION only if a .nvmrc file is
present and the user didn't provided a version to use (.ie typed `nvm
use`).

- Behavior before this fix :

nvm use
Found '.nvmrc' with version <v0.10.28>
N/A: version "N/A" is not yet installed.

You need to run "nvm install N/A" to install it before using it.

- Behavior after this fix :

nvm use
Found '.nvmrc' with version <v0.10.28>
N/A: version "v0.10.28" is not yet installed.

You need to run "nvm install v0.10.28" to install it before using it.
