[bug#61246] [PATCH] gnu: libgit2: Update to 1.5.1.

["André Batista" <nandre@riseup.net>]

* gnu/packages/version-control.scm (libgit2): Update to 1.5.1.
[source]: Remove snippet to comment out the "10 years ago" test, which
was removed on newer versions.
(libgit2-1.4): New variable. Update to 1.4.5.
(libgit2-1.3): Inherit from 'libgit2-1.4'. Update to 1.3.2.
(libgit2-1.1): Update to 1.1.1. Add back the snippet which comments out
the "10 years ago" test that remains on this older version.
* doc/guix.texi (Using a Custom Guix Channel): Add note and example
on how to exempt a local guix repository from git ownership checks.

+Note that you can specify a local directory on the @code{url} field above if
+the channel that you intend to use resides on a local file system.  However, in
+this case @{guix} checks said directory for ownership before any further
+processing.  This means that if the user is not the directory owner, but wants
+to use it as their default, they will then need to set it as a safe directory
+in their global git configuration file.  Otherwise, @command{guix} will refuse
+to even read it.  Supposing your system-wide local directory is at
+@code{/src/guix.git}, you would then create a git configuration file at
+@code{~/.gitconfig} with the following contents:

+@example
+[safe]
+        directory = /src/guix.git
+@end example

+This also applies to the root user.
