Please describe the problem.

After adding a gcrypt::rsync:// remote, git-annex-sync and git-annex-info crash with:

git-annex: bad url rsync://
CallStack (from HasCallStack):
  error, called at ./Git/Construct.hs:107:15 in main:Git.Construct

What steps will reproduce the problem?

git init
git annex init test
git remote add test gcrypt::rsync://
git annex sync

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

git-annex version: 8.20201127

done, it will no longer crash, and git-annex sync will work --Joey
