That is after the sit-for and before the `delete-other-windows'

     (sit-for 0.5)
     (delete-other-windows)

your frame has got smaller by one line?  The fact that it gets smaller
by _one_ line and Info is involved might relate this to the header line.
Unfortunately, it seems impossible to turn that line off by setting
`Info-use-header-line', so I don't know how to test this.  You could try
with a non-Info buffer displaying a header-line.

Maybe it's related to the KDE frame resizing problem you mentioned
earlier (I suppose you still get that after the merge).  Does changing
the font and/or changing the Info faces affect the behavior?
