Empty parameters are not included in curl and HTTP request snippets

[wilkinsona]

It's possible for a request to contain a parameter with no value. For example, http://localhost/test?foo contains the parameter foo with no value. You can also post a parameter with no value, for example curl -X POST http://localhost:8080/ -d 'foo='.

Neither the curl request snippet nor the HTTP request snippet handle valueless parameters correctly. In both cases the parameters are omitted entirely.
