[BUG] npm explore shell spawning without arguments immediately terminates (!isWindows)

[jasisk]

What / Why

The shell spawned by npm explore <package> (no additional arguments) terminates immediately.

When

npm explore <package>

Where

npm cli

How

The shell is spawned erroneously with the arguments ['-c', '']. This is because of a faulty args truthiness check rather than a length check.

Current Behavior

$ echo $SHLVL
1

$ npm explore packagename

$ echo $SHLVL
1

Steps to Reproduce

npm explore <packagename>

Expected Behavior

$ echo $SHLVL
1

$ npm explore packagename

Exploring /path/to/node_modules/packagename
Type 'exit' or ^D when finished

$ echo $SHLVL
2
