Node: Suppress the node 7 Buffer DeprecationWarning for global scripts

[spelunk]

(node:87907) DeprecationWarning: Using Buffer without `new` will soon stop working. Use `new Buffer()`, or preferably `Buffer.from()`, `Buffer.allocUnsafe()` or `Buffer.alloc()` instead.

Shows up on the standard error every time I use certain command line tools like browserify and xlsx. I don't have write access to those node modules and hence can't change the command line scripts. Is there a way to suppress the warning that doesn't involve going back to an older version of node?

--no-deprecation

There is both --no-deprecation to silence just deprecation warnings and --no-warnings to silence _all_ warnings (deprecation or otherwise).

[spelunk]

@Fishrock123 @mscdex to be clear, since I currently install the modules globally to be able to use them on the command line, is the suggestion to clone the affected repos and modify the global bin scripts (e.g. https://github.com/substack/node-browserify/blob/master/bin/cmd.js for browserify) so the shebangs have --no-deprecation, then do some npm install -g on the local modules?

@spelunk Or submit a PR to the offending project to fix the Buffer usage and not have to change anything?

[spelunk]

Use new Buffer(), or preferably Buffer.from(), Buffer.allocUnsafe() or Buffer.alloc() instead.

Is there some note regarding when each of these options is appropriate?

[spelunk]
