SI-9127 Xlint doesn't think spaces are significant

For purposes of warning about missing interpolators,
such as `"$greeting"` when the intended code was `s"$greeting"`,
spaces are no longer significant.

The heuristic was previously intended to allow compileresque
strings, where the dollar sign is a common prefix.

Currently, the Xlint warning can be selectively disabled.
