[bug#56089] [PATCH] refresh: Repurpose '-L' for '--load-path'.

From: Ludovic Courtès
Subject: [bug#56089] [PATCH] refresh: Repurpose '-L' for '--load-path'.
Date: Sun, 19 Jun 2022 15:33:13 +0200

This incompatible change fixes an inconsistency with other commands
where '-L' is short for '--load-path'.

* guix/scripts/refresh.scm (%options): Add --load-path option from
%STANDARD-BUILD-OPTIONS.  Remove #\L shortcut for --list-updaters, and
remove --load-path option that lacked the #\L shortcut.
(show-help): Update accordingly.
* doc/guix.texi (Invoking guix refresh): Update accordingly.

This patch fixes a CLI inconsistency.  It introduces an incompatibility,
but one that's probably acceptable: '--list-updaters' is rarely used.

Commit 21f4fbdd8453e489fb89825c4226a0a0bda2bc17 purposefully
introduced '--load-path' without the '-L' shorthand; in hindsight,
reclaiming '-L' for '--load-path' sounds preferable to me.
