[ICI] forall on gettokens

[George P. <geo...@ci...>]

Am I doing something wrong here?
gettokens on an empty string appears to generate an array of length 1, 
but if I loop over that array, it behaves like it's of length 0.

Here's the code:

auto line;
auto f;
auto word;
while (line = getline())
{
    printf("<%s>", line);
    f = sopen(line);
    line = gettokens(f);
    close(f);
    printf("<%d>\n", nels(line));
    forall (word in line)
        printf("<<<%s>>>", word);
    put("\n");
}


Here's the input--three lines, the middle one empty:

hello there

we would like


Here's the output:

<hello there><2>
<<<hello>>><<<there>>>
<><1>

<we would like><3>
<<<we>>><<<would>>><<<like>>>
