This must be a very old entry.

The default height was changed from 40 to 35 by Chong and from 35 to
36 by Eli.  I now updated the value given by the manual of the release
branch.

28 lines is strange indeed.

Evaluating (frame-height) with emacs -Q should yield 36.  What does it
give for you?  And what is your value of (window-total-height) for the
initial window?  It's 35 here.
