demandimport: fix level passed to loader of sub-modules
As the fromlist gives the names of sub-modules, they should be searched in
the parent directory of the package's __init__.py, which is level=1.
I got the following error by rewriting hgweb to use absolute_import, where
the "mercurial" package is referenced as ".." (level=2):
ValueError: Attempted relative import beyond toplevel package
I know little about the import mechanism, but this change seems correct.
Before this patch, the following code did import the os module with no error:
from mercurial import demandimport
demandimport.enable()
from mercurial import os
print os.name
