Clean up glibc version numbers in manual

I'm not going to get into discussions of the past.

That seems potentially reasonable on its face.  But I think we first need
to figure out what to do about EDITION and ISBN and how it all relates to
the FSF's printed editions.  I haven't talked to anyone there about printed
manuals since last millenium.  They appear to be selling a two-volume
version and I have no idea how the volume split works.  I think we should
figure all that out.  

If we can't figure it out very soon, then in the interim we should probably
adopt your suggestion and also remove or (@comment out) EDITION and ISBN
and their uses, along with anything else that mentions printed editions.


Thanks,
Roland
