bug#23696: 25.0.94; Wrong quoting in several doc strings

[Stephen Berman]

I found cases of quoting in several doc strings that appear in the
*Help* buffer as curved quotes, I believe wrongly.  I would like to ask
for confirmation that the fixes below are correct and, if so, approval
to push them to emacs-25.  Note that the patch for vhdl-mode also
removes a quote that is at least superfluous, if not incorrect.

[Paul Eggert]

Thanks, those doc fixes all look good, and I installed them into 
emacs-25 in your name.
