stringify adds leading newline

[petemill]

.parse cannot parse the output of .stringify as it outputs with a leading newline.

Here is a reproducible case:

let sshConfig = require('ssh-config')
let config = sshConfig.parse('');
config.append({ Host: '*', IdentifyFile: '~/.ssh/all' });
let output = sshConfig.stringify(config);

This produces an output with a leading newline. If we then try and parse that output with .parse, we get a corrupted object (which is probably another issue). If we remove the newline manually, .parse works correctly.

I'm thinking the issue is with .stringify

If this fix could be merged and published to npm @dotnil , that would be great. Thanks

@petemill I tried to reproduce the other issue you mentioned with the code below but with no luck.

var obj = sshConfig.parse('')
obj.append({ Host: '*', IdentifyFile: '~/.ssh/all' })
console.log(sshConfig.parse(sshConfig.stringify(obj)))
// { '0': { Host: '*', IdentifyFile: '~/.ssh/all' } }

Theoretically, an leading newline in the text being fed to sshConfig.parse shouldn't cause any issue because the text will be trimmed first. see https://github.com/dotnil/ssh-config/blob/master/index.js#L168
