Trailing Whitespace

One of the most frustrating things to deal with is the trailing space. Trailing spaces are such a pain because

• They can screw up string literals
• They can break expectations in a text editor (i.e. jumping to a new line or the end of the line)
• They can actually break programming languages
• They are just unflattering

However, in Vim, it takes one autocmd to alleviate this.

augroup spaces
autocmd!
autocmd BufWritePre \* %s/s+$//e
augroup END

On every buffer save substitute spaces at the end of the line with nothing. Easy!
