bug#36884: Default python mode with electric-indent-mode sometimes indents empty lines

[Jarosław Rzeszótko]

M-x about-emacs shows:

GNU Emacs 26.1 (build 2, x86_64-pc-linux-gnu, GTK+ Version 3.24.4) of 2019-02-03, modified by Debian

C-h k [RET] shows that it is bound to the "newline" function. I get the same behavior with --no-init.

Cheers,

Jarek

Hi Jarosław,

python-mode.el developer here, just being interested.

AFAIU electric-indent-mode doesn't run a timer, cursor position alone
would not trigger it.

Assume there is a command used from pos. Which? BTW the key alone
doesn't tell enough, as RET and C-j changed binding recently. Reporting
Emacs version will be useful.

Thanks,

Andreas
