VSCode "Format Code" causes tslint failure with (old-school) type assertions

Preceded by https://github.com/Microsoft/vscode-tslint/issues/69 and microsoft/vscode#10296

TypeScript Version: 1.8.0

Code

If I have code like this:

const bar = <Bar> Thing.getFoo();

and then "Format Code" in VSCode (alt-shift-F on Mac), I get this:

const bar = <Bar>Thing.getFoo();

Expected behavior:

The spacing should not have been changed. (Note: without a specific setting, this causes a failure with tslint.)

Actual behavior:

The space after the old-school/bracket-style type assertion is removed, causing a tslint error.

Looks like this isn't currently configurable, but is controlled by the noSpaceAfterTypeAssertion rule

The current behavior is the intended design. this is similar to C# cast expression formatting in VS for instance. the request here is to add a new formatter option to add a space after type assertion.
