Currently, QuestionHelper trims all answers (see eg. https://github.com/symfony/symfony/blob/master/src/Symfony/Component/Console/Helper/QuestionHelper.php#L108 ). Can we add a possibility to ask for a value that starts or ends with whitespace?
The actual usecase is for example asking for a password. We do not want to restrict users to use only passwords that do not start or end with whitespace.
PasswordType has this feature by default - see https://github.com/symfony/symfony/blob/master/src/Symfony/Component/Form/Extension/Core/Type/PasswordType.php#L38 .
The QuestionHelper::doAsk() method is already quite complex but I guess we could add some logic there to check whether Question has flag trimAnswer set or not.
What do you think?
