Old git URLs

Hello, I have just discovered that old git URLs, mentioned in various web pages and manuals do not work. For example, git clone git://common-lisp.net/projects/asdf/asdf.git fails with fatal: unable to connect to common-lisp.net: common-lisp.net[0: 148.251.248.130]: errno=Connection refused common-lisp.net[1: 2a01:4f8:200:4310::30]: errno=Network is unreachable New format, as suggested at GitLab project pages: git clone git@common-lisp.net:asdf/asdf.git works. It makes sense, if technically possible, to support old addresses too. Best regards, - Anton
