Request/response header in style of "<header" is transposed from documenation

[brianv0]

The documenation states that the following are appropriate for documenting a request/response header:

requestheader, reqheader, >header
responseheader, resheader, <header

The code diverges from this:

httpdomain/sphinxcontrib/httpdomain.py

Lines 286 to 291 in 47cee9d

	GroupedField('requestheader', label='Request Headers',
	rolename='header',
	names=('<header', 'reqheader', 'requestheader')),
	GroupedField('responseheader', label='Response Headers',
	rolename='header',
	names=('>header', 'resheader', 'responseheader')),

I'm not sure of this is a doc fix or a code fix.
