Emacs: apply "expand-filename" on "default-directory". "default-directory" may has home directory("~") relative path in some runtime environment(or emacs revision ?), so expand-filename is required.

#!/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
