Apparently, it is:

sh-4.0$ touch "x *"
sh-4.0$ FOO=`ls`;echo "$FOO"|od
0000000 020170 005052
0000004
sh-4.0$ BAR="`ls`"; echo "$BAR"|od
0000000 020170 005052
0000004

There might be some corner cases tho.  Test before puting into
production (newlines/control chars in file names, different versions of
shell, different set/shopt options, changes in IFS etc).
