[PATCH] Documentation: clarify that git-commit only works with tracked files

[Jonathan Nieder <jrnieder@uchicago.edu>]

A user unfamiliar with CVS might not realize that a git-add is
needed before commiting new files.  So emphasize that "git commit
<path>..." only commits files already in the index.

	I keep on forgetting and getting annoyed when "git commit
	newfile.c" does not work.  From the same confusion I suggested
	git commit -A without really thinking about what it meant.
	This change should make the behavior easier to understand
	and remember.  Thanks for the help.
