The man page says:
The shell does not exit if the command that fails is part of the
command list immediately following a while or until keyword,
part of the test following the if or elif reserved words,
part of any command executed in a && or || list except the
command following the final && or ||, any command in a
pipeline but the last, or if the command's return value is being
inverted with !.
The fact that [ exits with 1 seems to be covered by the above passage for
-e.
