[PATCHv4 3/5] git-sh-setup: introduce say() for quiet options

[Stephen Boyd <bebarino@gmail.com>]

Scripts should use say() when they want to output non-error messages.
This function helps future script writers easily implement a quiet
option by setting GIT_QUIET to enable suppression of non-error messages.
