[PATCH] git.txt: update description of the configuration mechanism

[Matthieu Moy <Matthieu.Moy@imag.fr>]

The old Git version where it appeared is not useful only to historians,
not to normal users. Also, the text was mentioning only the per-repo
config file, so add a mention of ~/.gitconfig. Describing in details the
system-wide, XDG and all would be counter-productive here, so reword the
description of the link to git-config to make it clear that it is not
only a list of configuration options.
