Please describe the problem.

The S3 special remote assumes that yout want to use HTTPS iff your service runs on port 443. This isn't true for most minio deployments.

What steps will reproduce the problem?

Attempt to add a S3 service using HTTPS and a port != 443 as special remote.

What version of git-annex are you using? On what operating system?

Version 7.20181121 on MacOS and 7.20190130-g024120065 on FreeBSD

Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

Yes. I only encountered the problem because git-annex works well enough for me that I want to put a lot more data into it.
