Force pull from subrepos

[Mina R Waheeb]

Here is an my workflow:

cd toplevel
hg init
hg convert http://svn.myserver/somerepo subrepo
echo subrepo = subrepo > .hgsub
hg add .hgsub
cd subrepo
hg update # now we have the lastest tip from the converted repo (mirror,
read only)
cd ..
hg commit # now the .hgsubstate contains a specific version of the subrepo
hg update null

## The above commands i used to set up the main repo which everyone push to
it

## do normal clone in a dev machine
hg clone http://hg.myserver/toplevel # Now i have a copy

## I have cron job incrementally update the hg mirror daily
cd /path/to/toplevel/
hg convert http://svn.myserver/somerepo subrepo ## pull the svn updates from
the SVN server

## Now i go back to the cloned repo
hg pull # I got no changes because .hgsubstate is pointed to a specific
version
## then i have to do
cd subrepo # and add the default push url
hg pull
cd ..
hg commit # this will change the .hgsubstate to the current version in the
local copy

I know the above is designed functionally for the subrepo, but I just need
pull from all the subrepo (the tip) not pull the current version in the
.hgsubstate, because not every independently commit i do in subrepo i have
to do changeset for it in the toplevel repo!

What i said about the entry (idea) in .hgsubstate, when it fullzeros always
pull the tip.
