Install hooks quietly during developer setup
Install hooks quietly during developer setup

Remove extra echo messages.  Use the '-q' option to Git commands to
keep them quiet if nothing goes wrong.  This removes extra output
during developer setup that includes unnecessary and possibly
confusing information like the commit message of the hooks branch
head.  For example, lines like

  HEAD is now at ad08c20 Merge branch 'itk-hook-cleanup' into hooks

are not useful.
