Address git feature pull/track/checkout

[ChrisJStone]

There seems to be some confusion when to use feature pull/track/checkout commands as mentioned on the OP petervanderdoes has suggested that pull be dropped in the 2.0.0 release and to use track.

My thoughts

• Track is used when wanting to follow a particular feature on a remote.
• Pull is used when wanting to update a tracked branch from a remote.
• If wanting to look at a feature then checkout should be used.
