bad error message "TypeError: Usage: Buffer.concat(list, [length])"

[tj]

"array expected, passed " or something would be more obvious to assert that it's a type issue, something consistent throughout core for type issues would be nice. AFAIK no others use "Usage: ..."

Hm... I'd say that this is a bit questionable :) @tjfontaine thoughts?

[tj]

not a huge deal but every little bit of polish helps. from that message it could be length that is an invalid type, or the list, but doesn't really state what's actually wrong

[trevnorris]

Extracting the exact <type> passed would be too difficult. Maybe "Expected Buffer" or some such.

Fixed in d01a900 for v0.10, and merged in v0.12 and master with b0425f0 and a995a6a. Thank you @chrisdickinson!
