I'd like to see tab completion introduced for the commands -- while
the single-character aliases are nice, tab-completing is in my muscle
memory, as I suspect it is in many others, too.
I've written a very rudimentary completion script which merely
completes the command name in Bash: http://gist.github.com/445941
What are your thoughts on this? Would it be possible to get it bundled
with Rails? I'm not sure if there's a generic way to install this; on
Debian, placing the executable in /etc/bash_completion.d is enough.
