E.g. I can see that we might want to preserve the space in the above case (tho it presumes that the user really intended it to be the sig separator, which seems quite unlikely nowadays because AFAICT most users have no idea that such a thing even exists). But what about: M-> -- SPC hello world M-b M-b RET should this RET be interpreted as an intention to turn the "-- SPC" into a sig separator? Stefan
