Coverage remained the same at 84.599% when pulling 7c96781 on geekonloose:master into dab8ff6 on python-control:master.

It looks like the line style or something changed so that every line in the is marked as deleted then added.

Can you try to reset the line style back to the original so that we can see only those lines that changed? Much easier to track updates that way.

My editor was automatically formatting to pep8 format sorry for that. I have reformatted file as possible. I have checked with file compare in vs code (with the original file in python-control), it was able to show the changes. However, GitHub is showing so many deletions. If you want, I can provide line-numbers where I have made changes.

Can you just go back to the original file and only edit the lines that actually need to be changed? Just putting the lines changed in the PR comments won't let people see what actually changed if they do git diff.

Looks like 8f8565b fixed the problem but then 1f4885d changed it back?

Also: I suggest using keywords that are more descriptive than hw and hl. How about arrowhead_width and arrowhead_length?

ok I will do that.
