Trailing whitespace in {#each} removed when block is followed by additional content

[trbrc]

Example:

{#each ['dog', 'hen', 'fox', 'cat', 'pig', 'ant', 'cow', 'koi'] as value}
  <span>{value} </span>
{/each}

produces a space separated list that visually looks like dog hen fox cat pig ant cow koi. However, if you insert seemingly any content after the each block, such as the following:

{#each ['dog', 'hen', 'fox', 'cat', 'pig', 'ant', 'cow', 'koi'] as value}
  <span>{value} </span>
{/each}
owl

the space disappears and it looks like doghenfoxcatpigantcowkoi owl.

The generated c method changes like this:

		c() {
			span = element("span");
			t0 = text(ctx.value);
-			t1 = space();
		},

This sounds the same as long-standing issue #713. I tried briefly looking into it a couple times over the years (!) and each time gave up trying to understand the whitespace handling code in the compiler.
