We have a terminal room of TVI910 terminals, which are functionally
similiar to the Wyse 50. When using Gosling Emacs, we would have the
same problem as mentioned above ("spaces" in mode lines). We solved
the problem simply: by deleting Gosling Emacs off of disk, and
replacing it with GNU Emacs 17.56. Problem solved.  Q.E.D.
 Definitely a software problem and not a problem with the terminal. 

By the way, I got a letter from someone who claims that when termcap
support was added to Gosling Emacs, they didn't have a brain-damaged
terminal available, and since it was just an academic hack and they
had no idea anybody would actually try to SELL the thing, they didn't
bother putting in support for terminals with "magic cookies" (i.e.
terminals that eat a byte of display space for attributes, such as the
Wyse 50, Televideo line, Lear-Siegler, etc.).
