--redirect-warnings option appears to be broken

I tried various invocations but none seem to really work:

node −−redirect−warnings=file -p 'GLOBAL.foo = 1'      # Error: Cannot find module
node -p 'GLOBAL.foo = 1' −−redirect−warnings=file      # No error, no file written

@silverwind hi!

A minus sign in your commands is http://www.codetable.net/decimal/8722, but a minus sing from docs (and standard keyboard as well) is http://www.codetable.net/decimal/45.

If you try to execute these commands:

node --redirect-warnings=file -p 'GLOBAL.foo = 1'      # ok
node -p 'GLOBAL.foo = 1' --redirect-warnings=file      # ok

You'll get no errors. But if you'll try to execute this:

node −−help

You'll get the same error as in your case:

Error: Cannot find module '/Users/daynin/−−help'
    at Function.Module._resolveFilename (module.js:536:15)
    at Function.Module._load (module.js:466:25)
    at Function.Module.runMain (module.js:676:10)
    at startup (bootstrap_node.js:187:16)
    at bootstrap_node.js:608:3

Other command line tools cannot parse this minus sign as well

Indeed you're right. I have no idea how I was even able to write the unicode symbol. Sorry for the noise.

Ah, I remember: I copied it out of the HMTL mentioned in #18559 (comment).
