Since readline won't work an alternative needs to be found. A pure Go library would be ideal. But decent C bindings with a reasonable license would be fine too. This thread should collect requirements and decide on an alternative package.

• Left/Right arrow key support is the absolute minimum of what's needed.
• History support (built in or hackable).
• Auto complete support (built in or hackable). This could have varying degrees of awesomeness. Any would probably be preferable over none.
• Reverse i-search support (built in or hackable).

Things like my vim ~/.inputrc bindings are probably a lot cause (nooooo!).
