Arguably it's a bug that 'help read' doesn't mention the effect of
backslashes, other than what can be extrapolated from the description of
-r. It only says "The line is split into fields _as with word splitting_",
but word splitting doesn't recognize backslashes as special. It should not
be necessary to read the description of all options to infer the behaviour
of a command as used without them.

That isn't the function of `help'. The help documentation is intended to be
a quick reference, not to duplicate everything in the man page.
