Many versions of ps truncate lines at a certain length if they can't determine the terminal size. Since you're running
psfrom inside the backend, there's probably no terminal to check. Check the ps manual page to see if it supports an
optionlike -w (or multiple occurrences of -w) to increase the line length.
