InputGroup with no right element sets right padding of input element to zero

[alexanderchr]

Bug report

• Package version(s): master branch
• Browser and OS versions: NA

Steps to reproduce

1. Render an InputGroup

Actual behavior

The text input rendered by the InputGroup has 10px left padding and 0 right padding, thanks to https://github.com/palantir/blueprint/blob/master/packages/core/src/components/forms/inputGroup.tsx#L117.

Expected behavior

The text input rendered by the input group should have $input-padding-horizontal padding on both sides. (

blueprint/packages/core/src/components/forms/_common.scss

Line 91 in 85a42b2

padding: 0 $input-padding-horizontal;

)

I don't know if this is an issue in general, but it appeared to me when using DateInput as the inputs rendered through that component are 10px narrower than regular inputs.
