surf-extension sub-generator incorrectly defaulting auto-deploy to 1.0

[binduwavell]

This is what the prompt output looks like:

Auto deploy determines if the module is auto deployed upon startup. It should be true/false
See: http://docs.alfresco.com/5.1/concepts/dev-extensions-share-module-autodeploy.html
? What should auto deploy be set to? (1.0)

When accepting this we are told that we have provided an incorrect value. Reading the docs it appears that true or false should be provided. If that is the case, this should probably be a choice rather than an entry field as it is currently.
