You have to go into each subrepo and run hg update <revision> to get
them to the revision that you want recorded in .hgsubstate.  Then when
you run hg commit those revision automatically get recorded in
.hgsubstate.  It's a little awkward, and one of the reasons (IMHO) why
subrepos is a "feature of last resort."
