Now, we have 3 options for the `clone` and `fetch` commands:
--branches=none: Ignore branches and merge changesets, fetching only the clone tfs path
--branches=auto:(default) Manage merged changesets and initialize the merged branches
--branches=all: Manage merged changesets and initialize all the branches during the clone
+ clean and improve the doc
