[PATCH] Documentation: add a new man page for "git-help" and -i|--info option.

[Christian Couder <chriscool@tuxfamily.org>]

Option -i|--info for "git-help" is documented only in the new
"git-help.txt" man page, but this new man page is referenced
from the "--help" option documentation in the "git.txt" man page.

+======
+
+NAME
+----
+git-help - display help information about git
+
+SYNOPSIS
+--------
+'git help' [-a|--all|-i|--info] [COMMAND]
+
+DESCRIPTION
+-----------
+
+With no options and no COMMAND given, the synopsis of the 'git'
+command and a list of the most commonly used git commands are printed
+on the standard output.
+
+If the option '--all' or '-a' is given, then all available commands are
+printed on the standard output.
+
+If a git command is named, a manual page for that command is brought
+up. The 'man' program is used by default for this purpose, but this
+can be overriden by other options.
+
+Note that 'git --help ...' is identical as 'git help ...' because the
+former is internally converted into the latter.
+
+OPTIONS
+-------
+-a|--all::
+
+	Prints all the available commands on the standard output. This
+	option superseeds any other option.
+
+-i|--info::
+	Use the 'info' program to display the manual page, instead of
+	the 'man' program that is used by default.
+
+Author
+------
+Written by Junio C Hamano <gitster@pobox.com> and the git-list
+<git@vger.kernel.org>.
+
+Documentation
+-------------
+Initial documentation was part of the gitlink:git[7] man page.
+Christian Couder <chriscool@tuxfamily.org> extracted and rewrote it a
+little. Maintenance is done by the git-list <git@vger.kernel.org>.
