[PATCH v2 0/4] git-completion.bash: fixes on top of 'dl/complete-stash'

[Denton Liu <liu.denton@gmail.com>]

Gábor pointed out some potential fixes what's currently queued in
'dl/complete-stash'[0][1][2][3]. This series addresses those concerns.

Changes since v1:

* Make the commit message for "git-completion.bash: rename to
  $__git_cmd_idx" descriptive and accurate

* Drop "git-completion.bash: consolidate no-subcommand case for
  _git_stash()"

         In e94fb44042 (git-completion.bash: pass $__git_subcommand_idx from
         __git_main(), 2021-03-24), the $__git_subcommand_idx variable was
    -    introduced. Naming it after the index of the subcommand is flat-out
    -    wrong as this variable really holds the index of the git comand (e.g.
    -    "stash").
    +    introduced. Naming it after the index of the subcommand is needlessly
    +    confusing as, when this variable is used, it is in the completion

    +    the `remote` is referred to as the command and `add` is referred to as
    +    the subcommand.
     
         Rename this variable so that it's obvious it's about git commands. While
         we're at it, shorten up its name so that it's still readable without
