Re-merge a couple of changes from NetBSD 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. Also fix some warnings to be more in sync with NetBSD. Obtained from: NetBSD

Merge changes from upstream libedit. Here we update most of the files to at least match the version available in NetBSD's snapshot of 20091228. This version was chosen because it still doesn't include wide character support (UTF-8), which involves many changes and new files.

{readline,history}.h are in /usr/include/edit so as to not conflict with the GNU libreadline versions. To use the libedit readline(3) one should add "-I/usr/include/edit" to their Makefile (spelled "-I${DESTDIR}/${INCLUDEDIR}/edit" within the FreeBSD source tree). * Enable its use in the BSD licensed utilities that support readline(3). * To make it easier to sync libedit development with NetBSD, histedit.h is moved into libedit's directory as history shows shown we keep merging it into that location.
