Extensionless paths should return null or false

[huyinghuan]

In general,

mime.lookup('/path/to/file.css');  // ==>  text/css   the result is ok
mime.lookup('file.css'); // ==>  text/css   the result is ok
mime.lookup('.css'); // ==>  text/css   the result is ok
mime.lookup('css'); // ==>  text/css   the result is ok
//but
mime.lookup('path/to/css');  // ==>  text/css  . the result is　controversial

What do you suggest the behavior should be?

[huyinghuan]

I think it should be default value application/octet-stream when the parameter is a file path and it have not extension name.

I just ran into this issue with a path like /admin/new/text that I expected to be application/octet-stream instead of text/plain.

The mime-types library, a similar library to this one, also had the same issue. If someone wants to copy/view our fix to incorporate here: jshttp/mime-types@f5e2eb2
