`.nvmrc` is found and read through symlinks,
so a repository that commits `.nvmrc` as a symlink to a path outside itself
(eg, `../../.npmrc`)
made a plain `nvm use`, `nvm install`, or `nvm which`
(or `nvm-exec`, or the README's auto-switching shell hook)
print that file:
the invalid `.nvmrc` message shows everything that was parsed,
even with `--silent`,
and a one-line file was taken as the version,
which is printed in the "Found" message and in later errors.
A symlinked `.nvmrc` is still followed,
so linking to another version file
(eg, `.node-version`, or a parent directory's `.nvmrc`)
keeps working,
but its content is never shown,
and it is valid only if it names a version or an existing alias,
via a new `nvm_is_version_or_alias` helper.
