This patch reverts various local enhancements to libedit, such as:
* r212191 more expected behaviour of ed-delete-next-char
* r212235 <delete> key support
* r209217,r209219,r209224 completion improvements for sh(1)
* built-in "\033[1~" and "\033[4~" support (not sure how useful this is)
* .An macros in man pages

If the csh-style history expansion gets in, a "set -o histexpand" for sh
could be useful. I think this is not important enough to add all the
code for, but if we have the code anyway why not allow using it. On the
other hand, if we can replace it with stubs and is very simplistic,
perhaps it is better to stub it out and not change sh.
