Quotes in Content-Type cause "error generating code: error formatting Go code"

[FenTiger]

Sample api.yml:

openapi: "3.0.0"

info:
  version: 0.0.1
  title: example

paths:
  /object:
    get:
      responses:
        '200':
          content:
            "application/ld+json; profile=\"https://www.w3.org/ns/activitystreams\"":
              schema:
                type: string

Sample config.yml:

package: main
generate:
  gorilla-server: true
  strict-server: true
output: test.go

The result I get is

error generating code: error formatting Go code 
[ ... dump of the code it is trying to generate ... ]
: main.go:221:79: missing ',' in argument list (and 10 more errors)

The dumped code has some invalid syntax:

func (response GetObject200ApplicationLdPlusJSONProfilehttpswwwW3OrgnsactivitystreamsResponse) VisitGetObjectResponse(w http.ResponseWriter) error {
    w.Header().Set("Content-Type", "application/ld+json; profile="https://www.w3.org/ns/activitystreams"")
    w.WriteHeader(200)

This can be worked around by double-escaping the quotes in the input (ie using \\\" instead of \").
