read --lines

Good use case here:

It could have the semantics of xargs --no-run-if-empty

Although you still want the "else" clause to print nothing, so maybe it's not that much of a win?

From #843

I think read --lines is better than each. At least for now. Then you don't have to deal with the MAX ARGV length problem.

We have some tests for this

• read --lines
• read --lines --with-eol
• read --lines --qsn

Maybe wait until somebody needs it

This is basically for pipe -> array. We have write --qsn for array -> pipe. So it makes sense to have this for symmetry.

On a sidenote, is it possible to compile this with replxx instead of --without-readline?

[andychu]

That's #460
