Thanks, this is an improvement.  Two comments:
1. s/meaningful/supported/  ?
2. Should we explain the limitations of child frames on text terminals
   here as well?

I note that we use the terminology "TTY frame" in NEWS, and "text
terminal" in the manual above.  In other places, we talk about "text
frames".

Which terminology do we prefer, and does it help avoid any confusion if
we are consistent?
