For future reference, here is the quick and (extremely) dirty script I used to search and replace these URLs. I also did a manual check of the final diff and had to make some slight corrections. Feel free to use however you find convenient.

#!/usr/bin/env python3

import os
import re
import requests
import subprocess
import urllib

URL_RE = re.compile(br'http://[a-z0-9.]+')
EXCLUDE = [
    '.git',
]


done = set()

for dirpath, dirnames, filenames in os.walk(os.getcwd()):
    j = 0
    for i, dn in enumerate(dirnames):
        if dn in EXCLUDE:
            del dirnames[i - j]
            j += 1

    for fn in filenames:
        if fn.endswith('.mo'):
            continue

        path = os.path.join(dirpath, fn)
        print('%s' % path)
        with open(path, 'rb') as fp:
            for line in fp:
                pos = 0
                # TODO: Ports?
                while True:
                    match = URL_RE.search(line, pos)
                    if not match:
                        break
                    pos = match.end()

                    old = match.group(0).decode('ascii')
                    if old not in done:
                        o1 = urllib.parse.urlparse(old)
                        new = 'https://%s' % o1.netloc
                        print('  checking %s' % new)
                        try:
                            r = requests.head(new, allow_redirects=True, verify=True, timeout=10)

                                requests.exceptions.ReadTimeout):
                            pass
                        else:
                            if r.status_code == 200:
