Inconsistent space after raw regions

[Quinn Grier]

There is inconsistent space inserted after the raw formatter regions.
Try the following:

      \input texinfo
      @setfilename test.info
      @settitle test
      foo
      @html
      bar
      @end html
      @tex
      bar
      @end tex
      baz
      @bye

This gives "foo barbaz" when translated to HTML but "foo bar baz" when
translated to TeX with Texinfo 6.0, 5.2, and 4.13. It's unclear if this
would be considered a bug, but it's something that I found surprising.
