(sorry for the PM)
This 2nd patch fixes the case I described. Thanks.
However, a similar bug then happens with 92 columns
after your patch:
$ vim -f -g -u NONE -c 'set showbreak=: columns=92' bug-vim.txt
When pressing A in command mode to append text, the cursor
is after the end of line. It was working fine with 92 columns
prior to your patch. So it's still not right.
We are getting there.
So this only happens, if the TAB is the first char after the showbreak
value
has been drawn, right?
So try this patch.
Kind regards,
Christian
