Re: How to end text-insert undo segment after cursor jump (caused by mouse)? [SOLVED]

[David <emacs-newbie@hj.proberto.com>]

Hey Stefan, thanks for your help!

You were absolutely right, the issue was caused by evil layer. Your 
solution to set evil-want-fine-undo worked perfectly!

I went to emacs customization interface for this variable, I set it to 
Yes (non-nil) and clicked "Apply and Save" and voila, from that moment 
on I was able to undo up until the problematic point and the undo action 
no longer grouped everything between start and end of insert command, 
but recognized piece-wise undo segments.

Thanks again and have a great day,

David
