Pass filename to decoder for 'hg archive' (fixes issue267) Despite writing to a file descriptor, the check in the [decode] section needs a filename. localrepo.wwrite() still writes to the file descriptor.

#!/bin/sh

mkdir t
cd t
hg init
echo a > a
hg add a
hg commit -m test -d "1000000 0"
hg history
hg manifest
hg cat a
hg verify
