Subject: 30.0.50; cperl-mode problem with format
Date: Thu, 21 Sep 2023 11:26:32 -0300

After emacs -Q:
C-x C-f bug.pl
M-x cperl-mode
Try to type the following:
format TOP =
****
.

First, when hitting RET after the first line, point doesn't go to column
0.  I expected it to go to column 0.
Then, after hitting RET so I can type the '.', it goes to column 2
again.  I delete the indentation space, type . and hit RET, and again
. gets moved to column 2.  I expect it to stay put.

Thanks for spotting this.

It seems that format declarations were not adapted to
electric-indent-mode nor jit-lock-mode.  This caused errors when
functions in cperl-mode were called with "unfinished" format
declarations, i.e. while typing them.

This has now been fixed in the master branch.
