Symptoms:

1. In an empty line writing only space and than new-line (with cursor after space), the space will be moved to next line. The space in next line seems like auto-indentation at work (and thus correct), but the space in previous line should remain there.
2. In an empty line writing only space and placing the cursor back to the start of the line and than pressing new-line, there will be 2 spaces in next line. By placing the cursor again at start of line and pressing new-line it will double again the spaces in next line. Again, the doubling of spaces is auto-indentation working, but in this case I believe it to be wrong. Auto-indent should not trigger if cursor is placed at start of line.

This seems like an issue in auto-indentation implementation or it is getting confused in which order the space and new-line characters are. Maybe some array/vector that has reversed order?

It is difficult to explain the above with words (and I am not sure that I succeeded), so I made short video.
