setup.py: install packagescan before any mercurial modules is imported Further the installation of packagescan over demandload is moved to the packagescan module. I added as well few more comments in the packagescan module to avoid the wrong use of package scan in the future. Reason: mercurial.packagescan acts as fake mercurial.demandload during a py2exe run. Unfortunatly the import of mercurial.version in setup.py is done before mercurial.packagescan is installed. This results in few imports without mercurial.packagescan in charge and therefore not all dependend modules are detected when running mercurial.packagescan.getmodules later e.g. winerror is missed.
