To my surprise there apparently hasn't been support for bash command
line completion for the gem command. I've cobbled together a file that
add just that. See
Bash Completion for the gem Command | Michael Schürig
I've only tested it on Debian/Linux, on other Linux/Unix variants things
might work somewhat differently. Also, I don't even try to do
completion for gem names; doing that for remote gems would be much to
slow and I haven't looked into getting that information from the local
source_cache.
