When updating notes, without providing Content-Type: multipart/form-data, the PUT results in 400 missing body argument (even when provided).

Here is how you replicate using Python.

# Failes
import requests
res = requests.put('https://gitlab.com/api/v3/projects/187725/merge_requests/59639/notes/3006211', 
                   headers={'Authorization': 'Bearer TOKEN'}, data='body=hello+world')
print res.text
>>> {"message":"400 (Bad request) \"body\" not given"}

# Works
res = requests.put('https://gitlab.com/api/v3/projects/187725/merge_requests/59639/notes/3006211', 
                   headers={'Authorization': 'Bearer TOKEN', 'Content-Type': 'multipart/form-data'}, data='body=hello+world')
print res.status_code
>>> 200

GitLab API's should assume multipart/form-data when no Content-Type header is provided. The API does accept requests from other endpoints when no Content-Type header is provided, as far as I've experienced it is only the Update Notes endpoint.
