Better handling of whitespace lines at ends of sections

This is another bit of cosmetic functionality; prior to
this commit, when adding a new setting to a section, we'd
write it on the very last line before the next section,
even if there was a chunk of trailing whitespace lines
at the end of the existing section.  This was functional,
but the output was not always particularly pleasant for
human consumption.

This commit tweaks things so that we insert new settings
just before the final chunk of whitespace lines in an
existing section.  This keeps things a bit cleaner.
