Before setting $PS1, __git_ps1() uses a command substitution to
redirect the output from a printf into a variable. Spare the overhead
of fork()ing a subshell by using 'printf -v <var>' to directly assign
the output to that variable.
zsh's printf doesn't support the '-v <var>' option, so stick with the
command substitution when under zsh.
