[PATCH 2/2] Documentation: make git-sh-setup docs less scary

[Thomas Rast <trast@student.ethz.ch>]

At least one IRC user was scared away by the introductory "This is not
a command the end user would want to run.  Ever." to the point of not
reading on.

Reword it in a more matter-of-fact way that does not intentionally try
to scare the user away.  Since 46bac90 (Do not install shell libraries
executable, 2010-01-31) it is not executable anyway, so the end user
would get

  $ git sh-setup
  fatal: cannot exec 'git-sh-setup': Permission denied
