Looking back at the original message, it looks like the user included a
newline in an argument to clone, and the fetch must have stripped it out
(or ignored it in some other fashion), because data was retrieved from a
repository that doesn't have a newline in its name. Most likely, the
newline should just be prohibited in the URL in the config file in the
first place, and we shouldn't be able to get to the point of writing a
FETCH_HEAD with that value.
