Following the coding conventions/styles used in the syntastic core:
* Use 4 space indents.
* Don't use abbreviated keywords - e.g. use `endfunction`, not `endfun` (there's always room for more fun!).
* Dont use `l:` prefixes for variables unless actually required (i.e. almost never).
* Code for maintainabiliy. We would rather a function be a couple of lines longer and have (for example) some [explaining variables](http://www.refactoring.com/catalog/introduceExplainingVariable.html) to aid readability.
# Syntax checker style notes
The preferred style for error format strings is one "clause" per line. E.g.
(from the coffeelint checker):
let errorformat = '%E%f:%l:%c: %trror: %m,' .
\ 'Syntax%trror: In %f\, %m on line %l,' .
\ '%EError: In %f\, Parse error on line %l: %m,' .
