A few minor wording adjustments. Please update the CSR accordingly and I'll
review it too.

Editorial: the run of italicized words makes this a bit hard to follow. Suggest:
In Perl, <i>free-spacing mode</i> (which is called <i>comments mode</i> in
this class)

I think this is good, but 1) it would probably be better placed in the "In this
mode" paragraph above, around line 825; and 2) it's normative so it shouldn't
say "Note that" (which makes it sound informative).
I'd also reword the second sentence a bit, something like
Such whitespace needs to be escaped in order to be considered significant.
