* Per discussion in #3075: if `sourceFiles` is unspecified, but `filename` is, use `filename`; output null instead of an empty string for `sources` or `sourceRoot` * Update source map tests to reflect that now we return null instead of empty strings; check generated sources array * Update source map documentation; still leave more obscure options undocumented * Follow the TypeScript compiler’s example regarding v3SourceMap, but output empty strings instead of made-up filenames * Have `sources` default to ‘<anonymous>’
