ng-maxlength validator does not respect/allow negative values

[petejohanson]

The standard maxlength attribute on <input> allows specifying a negative value to provide the default behaviour (i.e. unlimited length). For using a databound/dynamic value for ng-maxlength, I need the ability to allow an unlimited length as an option. However, with the current code, if you add an ng-maxlength attribute the only way to allow an unlimited length is to default it to some hardcoded very large value.

Ideally, I could do:

<input type="text" ng-maxlength="{{validation.maxlength || -1}}"></input>

And have it work as expected. Currently, with 1.3.1, this results in an invalid input regardless of the length.

We should evaluate this again once we have fixed the current bugs / regressions with input et. al.

@gkalpak Thanks, that looks like it bring things inline w/ my expectations.
