Basically the title. When writing .. it is converted to …. Also every string being any amount of dots is also being converted to …, even when it makes no sense.

.. -> ..
../relative/path/file.txt -> ../relative/path/file.txt
................................... (used as visual separator) -> ...................................

Automatically changing ... to the otherwise hard to type ellipsis symbol … is a good idea, but everything else should, not be changed.
