[PATCH] Clarify the git-branch documentation of default start-point

[Martin Nordholts <enselic@gmail.com>]

For someone not deeply into git it is easy to assume that start-point
of git-branch will deafult to origin/remotebranch when executing the
following command sequence:

  git checkout origin/remotebranch
  git branch localbranch

This change clarifies the git-branch documentation regarding this.
