25.0.92; Movement commands leave cursor in invisible line |
|

Hello,
I try to give a recipe resembling a bug in Magit concerning hidden lines
and cursor movement. In some buffer (emacs -Q) do
(insert "111" "\n222\n"
(propertize "333\n444\n\n" 'invisible t)
"555\n666\n")
and move around with C-n, C-p. Then the cursor will appear over the
first "5" but point is actually located inside the invisible area. This
is the cause of our trouble.
(setq line-move-visual t) helps, but setting (setq goal-column 0) makes
it appear again.
For reference, this is the original report in Magit (including
screenshots):
https://github.com/magit/magit/issues/2592
Thanks,
Michael.

More information was requested, but none was given within 6 weeks, so
I'm closing this bug. If there is anything more to do here, please
reply to this email (use "Reply to all" in your email client) and we can
reopen the bug report.
Best regards,
Stefan Kangas
