[PATCH] http.c: Fix problem with repeated calls of http_init

From: Julian Phillips <julian@quantumfyre.co.uk>
Date: Apr 29, 2007, 02:46 UTC
Message-ID: <20070429025059.2315.98407.julian@quantumfyre.co.uk>

Calling http_init after calling http_cleanup causes a segfault. This is due to the pragma_header curl_slist being freed but not being set to NULL. The subsequent call to http_init tries to setup the slist again, but it now points to an invalid memory location.

This doesn't cause any problems in current git as far as I know.  It does however break my C fetch when using http.
