This changeset refactors el_bind_key_in_metamap() into two functions,
adding el_bind_key(), to provide the ability for the user to bind keys
in both the regular and the meta-key maps.
Several useful, but previously internal, functions have been made global to
facilitate the example code mentioned above. These are likely useful to the
user of this library as well:
el_print_columns() - Display words in columns across a tty_cols wide screen.
el_ring_bell() - Can be used as default key binding function.
el_find_word() - Returns a copy of the word at rl_point.
=====================
Lots of minor fixes and additions:
* Bump version info in configure.ac
* User editline.h added, installs to $prefix/include/editline.h
- Based on Debian package version, but heavily updated.
* Manpage installs to $prefix/share/man/man3/editline.3
- Also slightly updated with contents from Debian package.
* Revised README to mention existing Debian package, also cleaned
out the old README, which now lives in doc/README
* Add TODO file.
* Fix package description and make dist to bzip2 tarballs.
