Support .editorconfig's continuation_indent_size

[JLLeitschuh]

According to ktlint both of these are valid:

fun Project.`spotless`(configure: com.diffplug.gradle.spotless.SpotlessExtension.() -> Unit = {}) =
    extensions.getByName<com.diffplug.gradle.spotless.SpotlessExtension>("spotless").apply { configure() }

fun Project.`spotless`(configure: com.diffplug.gradle.spotless.SpotlessExtension.() -> Unit = {}) =
        extensions.getByName<com.diffplug.gradle.spotless.SpotlessExtension>("spotless").apply { configure() }

Similarly both of these are valid:

val someSet = setOf(
    "a"
)

val someSet = setOf(
        "a"
)

Yeah, support for .editorconfig's continuation_indent_size is not implemented yet (IndentationRule). It would be very nice to have, though.

The link you posted is dead.
