TestValidateFormat fails in 1.2.3

[QuLogic]

This used to pass in 1.2.1:

$ go test -run TestValidateFormat
--- FAIL: TestValidateFormat (0.00s)
    checkmail_test.go:94: " florian@carrere.cc" => expected error
    checkmail_test.go:94: "florian@carrere.cc " => expected error
    checkmail_test.go:94: " test@gmail.com" => expected error
FAIL
FAIL	github.com/badoux/checkmail	0.003s

Bisect says 9c951e8 or #31 (but there were many build failures in between, so may or may not be true.)

I'm seeing the same issue - the regexp change causes the failure.

Still broken in 1.2.4 as well.
