Consistency++

Browse Source 
* Only use if/end blocks for things longer than one line.
 * Only use inline `[ foo ]; and bar` style when `bar` is `return`. Break the `and`/`or` onto a second line for anything that actually has a side effect.
 * More consistent use of `echo` flags.
 * Don't use `pwd` when `$PWD` will do.
