Subject: bug#35943: 26.2; `count-lines-page' gives wrong line count (off by one)
Date: Tue, 28 May 2019 14:40:11 +0200 [thread overview]
Message-ID: <CADwFkmmN0CO1cMLyPzq-KSKyyg9Yc8pEeGwrn-y42chMOEK58Q@mail.gmail.com> (raw)
There seems to be an off by one error in `count-lines-page'.
Steps to reproduce:
1. Run emacs -Q
2. Evaluate the following in the scratch buffer:
(with-temp-buffer
(insert "Page 1/3
^L
Page 2/3
^L
Page 3/3")
(forward-page)
(count-lines-page))
NB. Convert "^L" to the actual control characters.
3. Result:
"Page has 2 lines (2 + 0)"
4. Expected result:
"Page has 1 lines (1 + 0)"
Thanks,
Stefan Kangas
