snapshot: extract parent chain computation

The final step of this series is to include chain related to "prev" in the
search. Before adding that code we do some simple code movement to clarify the
next diff.

scratchnodes() {
  for node in `find ../repo/.hg/scratchbranches/index/nodemap/* | sort`; do
     echo ${node##*/} `cat $node`
  done
}

scratchbookmarks() {
  for bookmark in `find ../repo/.hg/scratchbranches/index/bookmarkmap/* -type f | sort`; do
     echo "${bookmark##*/bookmarkmap/} `cat $bookmark`"
  done
}
