2012-06-29T03:01:38+00:00

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.

Merge the following changes from NetBSD:

2007-03-11T21:47:40+00:00

history.c 1.32:
  # Fix memory leak found by valgrind (Julien Torres)
map.c 1.24:
  # fix debugging printf format.
read.c 1.40:
  # Fix bug with multiple pending el_pushes. Reported by Julien Torres.
tty.c 1.24:
  # Coverity CID 1216: Prevent negative index use.
