>Description:
	The $TERMCAP variable generated with eval `tset -s` is
missing some fields, specifically the ``longname'' field if it has
spaces in it. This causes "tput longname" to print something like
"sun" instead of "Sun Workstation Console" if you've generated the
$TERMCAP from "tset -s". (If tput reads /usr/share/misc/termcap
directly because you haven't set a termcap, longname does work)
	It appears that tset/wrterm.c is removing all terminal names
(separated by |'s) with whitespace in them. So, when you generate
a $TERMCAP with -s or -S, you miss out on the longname.

>How-To-Repeat:
% set term=vt100
% echo "$TERMCAP"
TERMCAP: Undefined variable.
% tput longname
dec vt100
% eval `tset -s`
% echo "$TERMCAP"
vt100|dec-vt100|vt100-am|vt100am:bl=^G:...
% tput longname
vt100am

>Fix:
	Remove the whitespace terminal name removal code from
tset/wrterm.c, so that the full termcap is written. Or change
it so that whitespace is \ protected (like the code further on
in that function does.)

State-Changed-Why:  
PR unsolvable, due to differences in the way that shells interpret 
quotes in backticks (the solution tried was to wrap the output of 
wrtermcap() in quotes, and permit whitespace in the terminal description 
fields. this broke when invoked as set foo=(`tset -S`) - the single 
quotes  in the output of test -S don't get parsed correctly. PR submitter (me :) is happy 
with this answer.
