Great, so you jumped on your keyboard to express your violent agreement. ;-)

At any rate, it looks like your and my proposals for such a
line-wrapping-without-breaking case, while perhaps interesting, do not
correspond to the bug reported.

It appears that the OP was indeed about face extension across (hard) line breaks
into indented text on the next line.

That was what my original response was to: If it hurts, don't do it; and let's
not assume that whitespace should not show the face attributes of the adjacent
text just because it represents indentation.
