Sublime has the settings: `trim_trailing_white_space_on_save` and `ensure_newline_at_eof_on_save`, I found these very satisfactory.

But there's almost certainly a ST extension for your particular taste.

I actually want it to trigger on each line when hitting return. It really helps with macros you can write when text munging. I didn't spend as much time as I would have liked looking at each editor but a command-key that deletes all ending whitspace on a line would also be acceptable.

For vim you can bind: `:%s/\s/+$//e`

I usually have ST and vim open at the same time myself.

I use the editorconfig plugin at work. You have an .editorconfig file at the base of your projects and everyones text editor gets the same settings on a per-project basis.

One of the default settings is to trim excess whitespaces.
