MFC r238377:

Merge libedit adjustment from NetBSD.

On recent versions of NetBSD's libedit, el_gets
now sets el_len to -1 on error so we can
distinguish between a NULL string and an error.

This fixes sh from exiting with newer versions
of libedit now allowing EINTR to return.

Obtained from: NetBSD
