Does seem a bit inconsistent.

I think it'd be quite foolish to assume that every extant and future
version of libxml2 will share this glitch.  Probably should use
logic more like pg_strip_crlf(), although we can't use that directly.

Would it ever be the case that trailing whitespace would be valid
data?  In a bit of testing, it seems like that could be true in
CONTENT mode but not DOCUMENT mode.
