Info Top File Format Problem

[Jonathan Levi]

Whe I open an Info window: In the * Menu, the "Text Creation and
manipulation" section and subsequent sections up to the Emacs section
are misformatted. Whereas the end of the TeX section appears normal, i.e.,

* vptovf: (web2c)vptovf invocation.             Virtual pl -> virtual font.
* weave: (web2c)weave invocation.               WEB to TeX.

the next section looks as follows:

Text creation and manipulation
* DVI-to-Postscript: (dvips).                                           Transl
                                                                        ating
                                                                        TeX
                                                                        DVI
                                                                        files
                                                                        to
                                                                        PostSc

                                                                        fonts
                                                                        availa
                                                                        ble to
                                                                        TeX.
...

The misformatting continues through a number of sections, then gets
partially corrected:

* GNU LilyPond: (lilypond).                                             The
                                                                        GNU
                                                                        music
                                                                        typese
                                                                        tter.

                                                                        ry of
                                                                        music
                                                                        terms.
Finally, it resumes an entirely normal appearance at the Emacs section. 

Can anyone help me?

Thanks in advance,

Jonathan
