Spaces should not be removed for --help prologue message #49

Open lamao opened 6 years ago

lamao commented 6 years ago

I want display table like message with several nested spaces for indentaion, e.g.

AA BB  .. CC
DD EE  .. FF
...........
F  G   .. H

But multiple spaces are removed - only one is printed. I get ugly table like this

AA BB .. CC
DD EE .. FF
...........
F G .. H
 @Test
    fun testPrologue() {
        val actual = "D  F".trimMargin().wrapText(80)
        assertEquals("D  F", actual)
    }

This is intended behavior, but you can at least work around the space collapsing issue by using non-breaking spaces:

val actual = "D\u00a0\u00a0F".trimMargin().wrapText(80)
assertEquals("D  F", actual)

There's still the issue of newlines, however. Newlines are treated like spaces, except (in the latest release) double-newlines are preserved, like in markdown.

Perhaps it makes sense to add some additional markdown-like behavior, like a way to preserve single newlines, or a way to have pre-formatted blocks.
