bin/sh has been taught about el_gets setting the count to -1 on error, so now we can partially revert r238173 to reduce differences with NetBSD's implementation. Unfortunately NetBSD's libedit handling of EINTR (Revision 1.44 in read.c + SIGWINCH fixes) still causes trouble in bin/sh and other utilities and has to be avoided. MFC after: 1 month
