But that happens only if the face specifies a background color.=C2=A0 If it=
specifies, say, :underline instead, on GUI frames it just extends one
character cell beyond the last character, and on TTY frames it goes to
the end of the window, i.e. behaves inconsistently.=C2=A0 And with
display-fill-column-indicator-mode turned on, on GUI frames it goes
half-way till the fill column: yet another inconsistent behavior.

So if you think the current display looks good, how about making it
optional?=C2=A0 Then this could be turned off to avoid the inconsistent
display in those use cases where it matters.

It is possible to make it optional.=C2=A0 However, it seems to me tha= t this is a bug in the display engine that should be fixed anyway, don'= t you agree?
