Thanks, I have a few comments:

Why is it useful to remove this information?  The documentation of the
spell-checkers themselves leaves a lot to be desired, so asking the
users to go consult it might not be appreciated.  I'd rather add here
the missing info about the other spellers.

I agree, but instead of removing the information, how about replacing
it with the Emacs version?  Something like "ispell.el from Emacs %s".

The rest of the patch is fine with me.  Please wait for a few more
days before pushing, to give people time to comment.
