Every shell is a login shell on Mac OS X. And I symlink `.bash_login` to `.bashrc`, so that `.profile` is getting sourced for interactive Bash shells.

.bash_logout

eval printf '%.s-' {1..$COLUMNS}
clear

.bashrc

## General configuration
[[ -z $PROFILE_SETUP && -r $HOME/.profile ]] && . $HOME/.profile
#shopt -q login_shell && echo this is a login shell

## Branch name and status marker for Git repos
GIT_DIRTY () {
	git diff --quiet HEAD &>/dev/null
	[[ $? == 1 ]] && echo ":" || (echo "·"; false)
}
GIT_REPO () {
	local BRANCH
	BRANCH=$(git symbolic-ref HEAD 2> /dev/null)|| return
	echo ${BRANCH#refs/heads/}
}
