In at least one case a customer of ours added a domain including
a schema, as in “http://domain.tld/”. That is obviously incorrect, but
then they couldn't remove it using the dokku command:
$ dokku domains:remove app7 http://domain.tld/
sed: -e expression #1, char 9: unknown command: `/'
This patch changes the sed command to use the "\CregexpC" syntax. The
character used is a vertical pipe, which is far less likely to be used
in a URL. After the change:
$ dokku domains:remove app7 http://domain.tld/
-----> Removed http://domain.tld/ from app7
