1. You cannot. The mark doesnot know how you are going to use the block.
   The *_rect functions will work on the rectangle defined by point and mark.
   
2. To mark a rectangle containing all of

     xxxxxxxxxxx
     xxx
     xxxxx
     xxxxxxxx
     xx
   
   you need to insert whitespace at the last line.
   
A function like the attached goto_max_column might help.
It is available under jedmodes.sf.net/mode/csvutils/
