RE: PATCH: improve git switch documentation

quoted

   git branch switch
   git tag switch   // detach
   git commit switch   // detach

Why? You don't switch tags or commits. You switch only branches, 

Yes you do.
You can switch to branches, tags or commits.

If I remember correctly, "branch" is used in Subversion and CVS only for the creation of a branch.  Likewise "tag" for creating a tag.  
And I think they both use "update" to load the required branch/tag/commit into the current working area.

If git were to do that then I think we might get around some of this confusion.

In that case:
git branch = create a branch
git tag = create a tag

And then a new "update", so:
git update <branchname> = make the current working area contain a copy of the given branch, and similarly "git update <tagname>" or "git update <commit-id>"

In all these cases the keyword after "git" is definitely a verb, even where the actual word used could be either, and you need to look at all the definitions in the dictionary to check.
