Chase the vim6's update to 6.0i. Rejoice if_ruby has been fully
merged into vim6. :)

But unfortunately they seem to have missed including two files
regarding if_ruby in the vim 6.0i tarball, so I prepared the diff to
complete them. This problem has been reported to the vim development
team, and it seems their CVS repository already holds those files.

Hopefully the next release of vim6 will include them properly.
