If you mean the lack of quotations, then the behavior is well-defined and is presumably what was intended. Per POSIX,

> The print statement shall write the value of each expression argument onto the indicated output stream separated by the current output field separator (see variable OFS above), and terminated by the output record separator (see variable ORS above).

The default value for OFS is <space> and for ORS, <newline>.

No, lack of commas in output and broken filenames with spaces.

I see your point regarding spaces in names. Suppose I could use FILENAME. But I think my point was made.
