Parsing the output of programs which return filenames is the only

be careful. setting ifs is global, and changes ifs for the whole
command, and doesn't change the behavior of external programs.
so it is both less and more than you want.
I always change it back immediately; a nuisance in for() as it has to
be set before and re-set inside. I'm considering whether a new shell
builtin would be desirable, similar to ` but always splitting on
newlines and only newlines, regardless of $ifs.
