If a UTF-8 file starts with a BOM character, the changebar plugin always shows the first line as changed even if there is no change.

To reproduce this, create a file with some lines of text, set encoding to UTF-8 and set "Document -> Write Unicode BOM"; save the file and git add and commit. The changebar immediately (or when reloading the file) shows the first line as changed.
