[tex-k] errata.tex update from DEK

[Karl Berry]

FYI below from DEK. Don is not reviewing additional bug reports now. He
just found these two in errata.tex on his own, I guess. (I committed to TL
in r58682. There will be at least one more build.)

If anyone has any ideas about promoting the new C&T volumes, as he is
hoping, please discuss or write board at tug.org. E.g., I have no clue how
to reach libraries en masse about a donation. --thanks, karl.

I found and fixed two small typos in errata.tex. A corrected file is
  http://cs.stanford.edu/~knuth/errata.tex

The Jubilee Edition now is at the printer. Spiffy new covers have
been designed to go with it. I hope there are good ways to promote it,
in your circles, so that many copies will exist for future historians!

David [Fuchs] had a curious idea to donate copies to libraries. (Not
necessary for Stanford, since our librarian has already ordered a new
set.)  Most libraries will not purchase, if they already own a prior
printing, because they will have no idea how many changes have been
incorporated.  Libraries that don't already have a copy will perhaps
want to supplement their collection on "historic examples of beautiful
books devoted to the process of creating beautiful books", if the books
are donated.
