" visincr.vim: Visual-block incremented lists
" Author: Charles E. Campbell, Jr. Ph.D.
" Date: Sep 19, 2006
" Version: 17
"
" Visincr assumes that a block of numbers selected by a
" ctrl-v (visual block) has been selected for incrementing.
" This function will transform that block of numbers into
" an incrementing column starting from that topmost number
" in the visual block. Also handles dates, daynames, and
" monthnames.
"
" Fancy Stuff:
" * If the visual block is ragged right (as can happen when "$"
" is used to select the right hand side), the block will have
" spaces appended to straighten it out
" * If the strlen of the count exceeds the visual-block
" allotment of spaces, then additional spaces will be inserted
" * Handles leading tabs by using virtual column calculations
