wiz 6285cf0f68 Import of texinfo-4.5.
Major changes since 4.3:
* Language:
  . The ' (ASCII apostrophe/right quote) character is finally allowed in
    node and anchor names.  Thus, after installing this texinfo.tex,
    existing .aux files will cause errors!  Remove them and rerun TeX to
    generate good ones.
  . @value constructs are now expanded in the filename arguments to
    @include and @verbatiminclude.
* texinfo.tex:
  . @smallexample and the like now output in a smaller font (9pt) in all
    paper formats, not just @smallbook and @afourpaper.
  . new translation txi-tr.tex.
* info:
  . CTRL-H is treated like DEL in incremental search.
  . arrow keys once again work in isearch contexts under Solaris.
* infokey:
  . use .info key bindings before defaults.
  . allow prefix keys to be disabled.
Bug fixes all around.
