51904e2687
This change reinvents all the GNU Readline features I discovered that I couldn't live without, e.g. UTF-8, CTRL-R search and CTRL-Y yanking. It now feels just as good in terms of user interface from the subconscious workflow perspective. It's real nice to finally have an embeddable line reader that's actually good with a 30 kb footprint and a bsd-2 license. This change adds a directory to the examples folder, explaining how the new Python compiler may be used. Some of the bugs with Python binaries have been addressed but overall it's still a work in progress.
