[PATCH] remote-curl: Add sanity check for url

[Ramkumar Ramachandra <artagnon@gmail.com>]

Previously, `git remote-http foo` and subsquent commands would try to
work on a HTML page. This patch fixes the bug by making one assumption
about the URL handled by libcurl: it must contain the string "://"
