You're right that the doc isn't consistent, and thus isn't correct.

I'm not sure that the third char in histchars is really related to
what you want - but if your problem is that you want to set it without
setting anything in histchars[0] and histchars[1], then what is probably
the best way is to set those first two to some character that has a higher
priority meaning (ie: one interpreted and removed before history) so
that its unlikely (though not completely impossible) that you'll ever
enter one - certainly the meaning of ! would be disabled.

eg: histchars='^m^m#'

(which is typed as "histchars='^V^M^V^M#'" assuming you use vi
style editing - probably some other way if you inflict emacs upon
yourself).   ^M (ie: carriage-return) is not normally going to still be
there in an input line by the time history expansions are looked at.

I have no idea what you're getting at here, a # alone is just
a single character word that starts with # - remember that "word"
here is used in the technical case of the shell, which is any
sequence of characters not including any shell delimiters, or
any of those delimiters - so abc is a word, as is 123, or @@@
or #abc or #
