I've seen this "last character of hostname dropped" symptom
mentioned on the #git channel long time ago, but I do not
remember if somebody figured out what the problem was.  I know
that nobody did a patch to specifically fix it.

Among the changes since v1.3.0 that touches http-fetch.c the
only thing I can see that touches anything related to alternates
handling is this one, but I do not see anything obviously wrong
with it X-<.

    Implement safe_strncpy() as strlcpy() and use it more.
