Vim options.

Added smarttab option.
Use hex mode for ^A/^X.  Numbers with leading zeros are interpreted as
octals by default.  Usually this is the wrong thing.  Setting hex mode
works most of the time.
Don't jump to the start of the line when using H, L etc.
Use UTF-8 listchars.  [git://github.com/graywh/dotfiles.git]
