clone: move bookmarks and checkouts before pull help

The bookmark/checkout help actually split the pull help.
The subsequent verbose container is talking about pull too.
This change puts the pull help back together again.

There are a handful of cases here that require renaming a module so it
doesn't overlap with a stdlib module name. There are also some cycles
here that we should still endeavor to fix, and some cycles will be
hidden by deduplication algorithm in the cycle detector, so fixing
these may expose other cycles.
