Editorial: Normalize code spacing.

[rkirsling]

@devsnek pointed out that 14.6.13 step 10 has extremely odd spacing:

constructor(... args){ super (...args);}

Like Gus, I'd rather not battle over style here, but I think anyone can agree that that line needs fixing.

The first commit here fixes parentheses and braces to align with the style shown in 13.7.5.15's note. (Strictly speaking, this is more than necessary; even just removing spaces would be an improvement.)

The second commit normalizes a couple of ..., cases to our more typical … ,.

Matching the most popular community style seems like an automatic win to me; plus; the current styling doesn’t match any version of community style that has ever existed.

[devsnek]

on a side note, is there any reason that the default constructors are defined in terms of source text instead of algorithm steps?

(per editor's group discussion; some small editorial PRs can be merged without both editors signing off)

The spec doesn't define notation for building parse nodes. (And even if it did, the notation probably wouldn't be as compact and clear as defining by source text, at least in this case.)
