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

hg init
python -c 'print "confuse str.splitlines\nembedded\rnewline"' > a
hg ci -Ama -d '1 0'
echo clean diff >> a
hg ci -mb -d '2 0'
hg diff -r0 -r1
