freebsd-dev/lib/libedit/sig.h
Pedro F. Giffuni c4fff9dd3a Re-merge a couple of changes from NetBSD's libedit.
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.
