Make "git help" react to window size correctly
Currently the git "show commands" function will react to the environment
variable COLUMNS, or just default to a width of 80 characters.
That's just soo eighties. Nobody sane sets COLUMNS any more, unless they
need to support some stone-age software from before the age of steam
engines, SIGWINCH and TIOCGWINSZ.
So get with the new century, and use TIOCGWINSZ to get the terminal size.
