Feature request: automatic trailing whitespace trim

[Ethan Larson]

If I have text like this, with the cursor at the asterisk

SOME TEXT1
SOME TEXT *
SOME TEXT

And I hit down, then up then up, I expect the cursor to be before the “1”, not after the “1” because I always use editors with automatic whitespace trimming and options not to allow the cursor to go beyond the end of a line.

The “save after trimming whitespace” option isn’t good enough, because it doesn’t fix it as I go. This is a cursor control issue for me, not a file-saving issue.
