The uncommon case that this patch handles is enough whitespace being
on the first line of a paragraph to cause it to wrap.  In this case the
first non-space character will be wrapped onto the next line.

Runs that are skipped over still need to affect the wrapping position,
otherwise they won't affect further run positions.

Lines in ME_WrapHandleRun were removed because ME_CalcRunExtent is
already called unconditionally just before it in the call to
ME_WrapSizeRun.
