[PATCH 2/2 v2] (short) documentation for the testgit remote helper

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

While it's not a command meant to be used by actual users (hence, not
mentionned in git(1)), this command is a very precious help for
remote-helpers authors.

The best place for such technical doc is the source code, but users may
not find it without a link in a manpage.

change since v1: document environment variables for debugging, not
hacking the source code.

+NAME

+git-remote-testgit - Example remote-helper
+
+
+SYNOPSIS
+--------
+[verse]
+git clone testgit::<source-repo> [<destination>]
+
+DESCRIPTION
+-----------
+
+This command is a simple remote-helper, that is used both as a
+testcase for the remote-helper functionality, and as an example to
+show remote-helper authors one possible implementation.
+
+The best way to learn more is to read the comments and source code in
+'git-remote-testgit.py'.

+# To understand better the way things work, one can activate debug

+# GIT_TRANSPORT_HELPER_DEBUG and GIT_DEBUG_TESTGIT, to see messages
