allow blank lines at the end of a file

[joshhartigan]

this is a fairly common practice. some reasoning can be seen here: http://stackoverflow.com/questions/2287967/why-is-it-recommended-to-have-empty-line-in-the-end-of-file
here's 'proof' it is counted as an error:

Agree with this one. It's my understanding that a lot of UNIX utilities require the extra LF at the end of a file to determine if it's a text file or not.

100% agree with you guys about always terminating a file with an LF.

However, in the example @joshhartigan posted, x.js actually has two line breaks at the end of the file. Multiple consecutive line breaks are disallowed. I don't feel strongly about this rule, but I do think that:

function one (x) {
  return x
}

function two (x) {
  return x * 2
}

is better than:

function one (x) {
  return x
}


function two (x) {
  return x * 2
}

Agreed with @feross.

I personally feel strongly about this and feel there is no need to have continuous line breaks in a file.

[mafintosh]

Agreed. Current behavior seems fine.

Cool, I'm going to close this issue.
