Summary: gem outdated fails for gems that are outdated but have a prerelease
installed
Initial Comment:
$ sudo gem1.9 outdated --backtrace
ERROR: While executing gem ... (NoMethodError)
undefined method `first' for nil:NilClass
.../rubygems/commands/outdated_command.rb:26:in `block in execute'
.../rubygems/commands/outdated_command.rb:21:in `each'

/opt/local/bin/gem1.9:21:in `<main>'
That occurs on my machine because I have rails 3.0.0.beta3 and 2.3.5 installed,
but 2.3.6 is out.
I can fix this by updating Gem::Commands::OutdatedCommand to exclude
prereleases when listing the outdated gems. Not sure if you'll want to somehow
handle prereleases with gem outdated, tho.

Message:
I made a simple patch that fixes the bug but doesn't otherwise enhance outdated
to handle prereleases.
Eg. if a prerelease itself is outdated, I'm not sure how that would be handled.
I
think prereleases are ignored by Gem::SourceIndex.outdated. (Our bug happens
after that, during the printing of the outdated gems.)
