From ce9baf234f04d2f1d183edbdc14e4ee9da46d895 Mon Sep 17 00:00:00 2001 From: Denton Liu Date: Mon, 27 Apr 2020 02:44:08 -0400 Subject: [PATCH] push: unset PARSE_OPT_OPTARG for --recurse-submodules When the usage for `git push` is shown, it includes the following lines --recurse-submodules[=(check|on-demand|no)] control recursive pushing of submodules which seem to indicate that the argument for --recurse-submodules is optional. However, we cannot actually run that optiion without an argument: $ git push --recurse-submodules fatal: recurse-submodules missing parameter Unset PARSE_OPT_OPTARG so that it is clear that this option requires an argument. Since the parse-options machinery guarantees that an argument is present now, assume that `arg` is set in the else of option_parse_recurse_submodules().
