Some of these diffs touch the copyright year lines, we might as well update
the years in the same commit. What counts as a "significant change" for
copyright purposes? E.g. is the list of years of CVS commits a good
enough approximation?

Typographical changes for printed output.
Very little change made to the produced info files.
doc/faq.texi:
doc/library.texi:
doc/reference_manual.texi
doc/transition_guide.texi
doc/user_guide.texi
Change en dashes to --, em dashes to ---, minus sign as @minus{}.
(Rendered as -,--,- respectively in info.)
Use @: after `e.g.', `i.e.', etc. to indicate word space rather than
sentence space.
Change `...' to `@dots{}'.
Change " to `` or '' (other than in code). (Rendered as " in info.)
