[PATCH] git help -w should not create nohup.out

[Dmitry Potapov <dpotapov@gmail.com>]

git-help--browse uses 'nohup' to launch some browsers. If the output is not
redirected, 'nohup' creates 'nohup.out' and prints a warning about that. It
was mighty annoying to see this warning as well as to have empty nohup.out
files scattered everywhere you happened to use 'git help -w'.

This patch redirects the output to /dev/null when a GUI browser is launched
using the 'nohup' command; thus 'nohup.out' is not created.

Initially I thought to redict the output to $HOME/.git-nohup.out instead of
/dev/null, so no output will be lost if an error happen. But the only error
that a GUI browser may want to report to the stderr or stdout is a problem
inside Xlib (like connection to X display or something like that), and when
it happens you cannot run your favorite browser from the command line anyway.
So, it is very noticeably and no problem to diagnose without any nohup.out
created by git help.
