Depends on the attribute.

If I set :foreground, it is retained both under X and -nw. :background too.

If I set :underline, it is retained under -nw, but not under X. But that 
includes an older branch which I haven't merged master to for a while, 
which I use daily.

Underline similarly appears briefly during startup but then goes away. 
Same for :inverse-video. All under X (-nw keeps them).

Said branch doesn't touch anything display-related, so it should behave 
like master a few months ago.

The difference seems to be that the most recent master also does that to 
attributes :height and :family.
