shell: also do word splitting when -d DELIM is used

The original commit 3bef5d89b0 introduced an additional check
for an unset `opt_d` before doing word splitting. I'm unsure
why it's there in the first place, but the commit message also
describes a different behaviour than what -d actually does in
bash, while the code mostly does the right thing.

`opt_d` sets the line delimiter for read to stop reading and
should not affect word splitting.

Testcase:
$ echo qwe rty | { read -d Z a b; echo a:$a b:$b; }
a:qwe b:rty

function                                             old     new   delta
shell_builtin_read                                  1314    1304     -10
