dodgy in unix where filenames can contain \n.
under plan 9 you have to remember to set ifs to \n only,
which is awkward and error prone.

this stuff is better designed for interactive use than scripting,
but it still does an adequate job provided you remember the pitfalls.
rc is loads better like that than shells with trad semantics.

i like the way i can parse quoted names in the inferno shell.
various p9 utils have been outfitted to print quoted names
but they're only useful interactively without support from rc.
