bug#62821: 28.2; doc of `with-eval-after-load'

[Drew Adams]

Looking at the doc string and Elisp manual entry for this macro, I see
no mention that the first argument, LIBRARY, is evaluated (to produce a
symbol or string).  Please mention this in the doc.  There's really
nothing that would cause a user to suppose that s?he needs to quote a
symbol, for example.
