The PARAGRAPH type of span is dangerous, as concatenating
CharSequences that contain it may crash. We also don't use
other spans than SuggestionSpans, so we don't copy them.

...and test it.

Also at the same time, add a facility to create a SettingsValues for
test, and some minor performance improvement to surrounding
methods.

This is about as ad-hoc as it gets, but then again, what we want
is probably as ad-hoc as it gets.
All URL boxes I know of double as search bars, and not adding
automatic spaces there sucks (e.g. in Chrome URL bar).
And in other boxes actually you don't want to add a space if
it looks like a URL. QSB isn't even a search box, and it behaves
like this.

So I think this is actually the right answer to the problem.

Since the function has to be modified heavily but does a lot
of non-trivial work, add a wealth of comments explaining what
it does and why so as to facilitate understanding the changes
to come.

This should have on effect at all on behavior,
except an increase in performance.
