41" it highlights extraneaous whitespace and tabs (so you can easily remove
42" them), sets column length to a max of 78 characters, expands tabs, and sets
43" a tab width of 4 spaces.

45" *NOTE 1* this doesn't guarantee that your code with fit the style guidelines,
46" so you should still to double check everything, but it helps with a lot of
47" tedious stuff.
48
49" *NOTE 2* if you do actually NEED to use a tab, e.g., in a Makefile, enter
50" insert mode and type ctrl-v first, which will make tabs behave as expected

62" stuff to prevent the light blue highlighting from showing up at the end of
63" lines when you're in insert mode. i.e., everytime you enter a space as you're
64" entering text the highlighting will kick in, which can be annoying. this will
65" make the highlighting only show up if you finish editing and leave some extra
66" whitespace

73" optionally set a vertical line on column 79. anything on, or after the line
74" is over the limit. this can be useful as set tw=78 won't breakup existing
75" lines that are over the limit, and the user can also do certain things to
76" make lines go past the set textwidth, e.g., joining a line (shift-j or J)
