Update README and bump version to 1.14.0 for release.

When adding support for rl_reset_termial() the tty_info() code was also
refactored.  This however led to the introduction of a bug that caused
tty_cols to be set to zero.  This in turn caused c_possible() to fail
with SIGFPE in el_print_columns().

Regression was introduced in 1c89c9886c

+HowTo Build Minix Editline
+==========================
+
+Minix editline makes use of GNU configure tools, which includes autoconf, automake
+and libtool. This enables high levels of portability and ease of use In most cases
+all you need to do is unpack the tarball, enter the directory and type:
+
+    ./configure
+
+There are are, however, more options available.  For instance, sometimes it is useful
+to build editline as a static library, type:
+
+    ./configure --disable-shared
+
+By default editline employs a default handler for the TAB key, pressing it once
+completes to the nearest matching filename in the current working directory, or it
+can display a listing of possible completions.  For some uses this default is not
+desirable at all, type:
+
+    ./configure --disable-default-complete
+
+An even more common desire is to change the default install location.  By default all
+configure scripts setup /usr/local as the install "prefix", to change this type:
+
+    ./configure --prefix=/home/troglobit/tmp
+
+Advanced users are encouraged to read up on --libdir, --mandir, etc. in the GNU
+Configure and Build System.
+
+For more available options, type:
+
+    ./configure --help
+
+To build and install, simply type:
+
+    make
+
+followed by
+
+    sudo make install
+
+Good Luck!

-Before finding out about the Debian version I was on the lookout for a really
-small replacement for the GNU readline package. Not only was libreadline large
-and GPL:ed (instead of LGPL:ed), it also depends on libncurses, the resulting
-size was a bit too much for my embedded system.  I eventually stubmled upon the
-BSD libedit library, which was sufficient for a while, even though it too
-depends on libncurses.  I searched my soul and went back to where I, back in
-1996, started out -- Minix.  And there it was, a really small readline
-replacement!
+This version of the editline library is a fork off the Minix3 sources. Other
+know versions, often based off of the original comp.sources.unix posting are:
 
-In 2000 Jim Studt packaged libeditline for Debian[1], the exact origin of the
-Debian code base is unclear, see the Sid package[2] for details. There were
-some notable differences between that version and the upstream Minix sources,
-all of which have now been merged here.
+   * Debian libeditline, http://packages.qa.debian.org/e/editline.html
+   * Heimdal, http://www.h5l.org
+   * Festival speech-tools, http://festvox.org/festival/
+   * Steve Tell's editline patches, http://www.cs.unc.edu/~tell/dist.html
+
+The most intersting patches and bug fixes from each fork have been merged here.
+Outstanding issues are listed in the TODO file.
 
 An explanation of the version numbering may be in order.  I didn't know about
 the Debian version for quite some time, so I kept a different name for the
 package and a different versioning scheme.  In June 2009, I decided to line up
-alongside Debian, with the intent of merging the efforts.  Sorry for any

+
+Issues in need of work. Mostly compatibility with GNU readline, BSD libedit,
+http://www.thrysoee.dk/editline/, and usability improvements.
+
+Remember, the general idea is to keep Minix editline small.
+
+* Verify for 1.14.0 that custom completion handlers still work
+After reverting "fix" in 0.2.2 that made rl_complete() a function pointer we need to
+make sure the same functionality is still available with the new infrastructure.
+(Which is more inspired by BSD libedit and GNU readline.
+
+* Investigate GNU readline dependencies needed for "fileman" example
+The BSD libedit library has imported the GNU readline "fileman" example into its
+tree to demonstrate the abilities of that library.  This would also be quite useful
+for Minix editline.
+
+The first task is to investigate the depependencies and form TODO list items
+detailing what is missing and, if possible, proposals how to implement including any
+optional configure flags.
+
+* Instead of supporting multiline input, try the Emacs approach, line scrolling.
+
+* Add support for rl_bind_key(), currently only en editline specific el_bind_key() exists.
 
-* Port "fileman" example from BSD libedit, http://www.thrysoee.dk/editline/
-* Add support for rl_bind_key(), currently one needs to "hack" the Map[]
-* Add support for inhibiting completion: rl_inhibit_completion
 * Make "char *rl_prompt" globally visible.
+
 * Add support for rl_set_prompt().
+
 * Add support for --enable-utf8 to configure
+
 * Use strcmp(nl_langinfo(CODESET), "UTF-8") to look for utf8 capable terminal.
+
 * Implement simple UTF-8 parser according to http://www.cl.cam.ac.uk/~mgk25/unicode.html#utf-8

 .SS "User Interface"
-A program that uses this library provides a simple emacs-like editing
-interface to its users.
-A line may be edited before it is sent to the calling program by typing either
-control characters or escape sequences.
-A control character, shown as a caret followed by a letter, is typed by
-holding down the ``control'' key while the letter is typed.
-For example, ``^A'' is a control-A.
-An escape sequence is entered by typing the ``escape'' key followed by one or
-more characters.
-The escape key is abbreviated as ``ESC''.
-Note that unlike control keys, case matters in escape sequences; ``ESC\ F''
-is not the same as ``ESC\ f''.
