Stack Overflow Outage Postmortem

On a related note: Is there any easy way to tell Vim when in insert mode not to accept extra spaces at the end of a line, except a single one?

I've got of course checks in place that warn about trailing spaces and my Git hooks outright refuse a commit with trailing spaces. But it would be nice to catch that at the insert level.

You know, it may be cat who's typing.

Not exactly at insert mode, but this may be helpful:

    autocmd BufWritePre * :%s/\s\+$//e

Before you save a file, it removes all trailing whitespace (ironically using the same regex as in the article -- hasn't given me trouble yet though)
