Thanks, this sort of thing should be helpful. I see you haven't signed copyright 
papers for Bison, though. I assume you know how to jump through the hoops? If 
not, I can send you email as to how to get the ball rolling.

very likely to work with many version of->
should work with

Also, the Texinfo input should have two spaces after ".", if that's the style 
used elsewhere in the Bison manual.

Remove "This practice is not highly recommended, however." It conveys little 
info and isn't needed in the context of the paragraph.

Not sure what is being recommended here. A developer is supposed to list all 
versions of all generates the grammar is capable with, and test them all, but 
generate a tarball with one of them? Or generate multiple tarballs?

Perhaps supply a small example of the issue. That would clarify the intent, I 
expect.
