This is rather strange though it seems merely an aesthetic issue.
I use something like
(setq org-ellipsis " ")
to customize the ellipsis. However, whatever characters I choose, there is always a line under the new "ellipsis". For the above setting, it simply shows like this
* a Title___
I have tried to start emacs at the terminal with
-q option, but the problem always exists. Notice that the underline does not appear if I just use the default
.... I actually had this problem for some time now, and once in a while, a new update in org can eliminate the annoying underline, but then again it appears in the next update. My org is up to date as of today (8/23/2018). I'm using macOS high Sierra.
Can someone give me advice on how to remove the underline?
Thanks in advance!
