node-resolve incorrectly resolves module-paths like "./someFolder/" when there is a file of the same name

I have a situation (real-world, this exists in the http-proxy module), where the following two things are in the same directory:

http-proxy.js - a file
http-proxy - a folder containing an 'index.js' file

http-proxy.js contains  `require('./http-proxy/')`, which node.js resolves to `./http-proxy/index.js`. `node-resolve` on the other hand, incorrectly resolves it to `./http-proxy.js`.
