In some text editors (e.g. Kate, gedit), when auto indent is enabled, pressing return twice will leave a trailing whitespace (which I want):

if (code) {
....
....|
}

While others cater to the coding standard where trailing spaces (even in blank lines) aren't allowed:

if (code) {

....|
}

What annoys me about this is that if I arrow up after auto-indenting, the auto-indent is lost:

if (code) {
|
....
}

If I run vim and :set autoindent , I get the latter behavior.

My question is, how do I set vim to keep the trailing spaces rather than automatically removing them if they go unused?
