vi puzzles

[M.W. Chang]

I believe the new version of vim support column editing mode. I have 
accidentally turned it on, but I could never reproduce the keystrokes I 
accidentally touched. I guess it was not a popular feature, but I used 
column editing frequently with my Semware QEdit to ident Foxpro codes 
frequently. QEdit even support sorting of lines inside the marked column.
