This series adds a new command "switch" for switching branches, an
alternative for "git checkout".
v2 fixes the comments I got from v1. I think the range-diff below
summarizes it better than I do. No major changes though.

-+match it. Optionally a new branch could be created with either `-c` or
-+`-C`, or detach from any branch with `--detach`, along with switching.
++Switch to a specified branch. The working tree and the index are
++updated to match the branch. All new commits will be added to the tip
++of this branch.
++
++Optionally a new branch could be created with either `-c` or `-C`, or
++detach the working tree from any branch with `--detach`, along with
++switching.
++
++Switching branches does not require a clean index and working tree
++(i.e. no differences compared to 'HEAD'). The operation is aborted
++however if the switch leads to loss of local changes, unless told
++otherwise.
