I am not sure, why you insist on NULL handling. Traditionally, shell
scripts couldn't handle binary NULL. They were designed to handle "text"
files and usually required \n delimited lines (with a max line length
around 2048 I think).
The only command, I can think of, that produces NULL delimited output is
find -print0 together with xargs -0 and even these parameters are not
portable and in fact not even necessary. You can use "find -exec sh {}
... " that can handle any input without losing portability.
So handling NULL is a corner case, that you can't expect to work
reliably anyway and whether one likes system() or uses :read! is merely
a matter of taste and shouldn't make a difference, besides, I don't see,
how your code is "much less code" as you claimed initially.
