This commit ensures that we properly handle the case in which an input string is only a newline character. We now make a run of text by shaping a space rune and then drop the glyph/rune data from the space (keeping the line height and such). The prior behavior would shape zero runes, resulting in no output runs, and thus our logic for synthesizing a glyph for the newline would never execute while iterating the runs. I tried to restructure to instead catch whether there were zero runs after the iteration, but it came out much uglier and harder to understand that way.
