sorry for all the trouble caused.

Junio, do you think moving out the free() would be a better option? Setting it to NULL just so we can free() is rather contrived, I feel.

Subject: [PATCH] http.c: move free() out of cleanup block

Instead of initializing a variable (url) just so we can do a free() on
it, as in b202514 (http.c: avoid freeing an uninitialized pointer), we
move the free() out of cleanup block.
