If I enter let's say 3 spaces, then the word "test",
then press Enter, the next line will be indented. This
is fine, so far so good. If I then press Backspace
until I reach the first position of the line (in other
words: remove the indentation), and press Enter again,
the next line will be indented again.
I would like to have the ability to switch this
behavior off, so that indentation will not take place
when the current line is not indented / has no spaces
or tabs at the beginning of the line.
