stdout maxBuffer length exceeded (diff.js)

[Pavel311]

I ran into a error while comparing two branches with large amount of changes.

events.js:174
      throw er; // Unhandled 'error' event
      ^

RangeError [ERR_CHILD_PROCESS_STDIO_MAXBUFFER]: stdout maxBuffer length exceeded
    at Socket.onChildStdout (child_process.js:348:14)
    at Socket.emit (events.js:189:13)

    at readableAddChunk (_stream_readable.js:261:13)

I found similar problem with solution issue#68.

In diff.js:86 I changed

exec('git diff --raw -z ' + cmd, {cwd: opt.cwd}, function(err, stdout) {

to

exec('git diff --raw -z ' + cmd, {cwd: opt.cwd, maxBuffer: Infinity}, function(err, stdout) {

Now everything works.
