foo.texi preferred

[Karl Berry]

Can't remember if we already discussed this ...  if foo.texi (or
related), I think it should be preferred to foo, even when "foo" is
specified on the cmdline, since that's how the old makeinfo behaved.

$ cd .../texinfo/doc
$ echo >info
$ makeinfo info.texi
warning: Document without nodes.

(Where makeinfo = perl -x -I $txi/tp $txi/tp/texi2any.pl "$@".)

The list of suffixes C makeinfo checked is:
  ".txi",
  ".texinfo",
  ".texi",
  ".txinfo",
  "",

Thanks,
