[PATCH 7/9] Documentation: clarify branch creation

[Jonathan Nieder <jrnieder@gmail.com>]

The documentation seems to assume that the starting point for a new
branch is the tip of an existing (ordinary) branch, but that is not
the most common case.  More often, "git branch" is used to begin
a branch from a remote-tracking branch, a tag, or an interesting
commit (e.g. origin/pu^2).  Clarify the language so it can apply
to these cases.
