Re: [PATCH 1/2] completion: add a helper function to get config variables

SZEDER Gábor [off-list ref] writes:

+	for i in $(git --git-dir="$(__gitdir)" config --get-regexp "$section\..*" 2>/dev/null); do
 		case "$i" in
-		pretty.*)
-			i="${i#pretty.}"
+		$section.*)
+			i="${i#$section.}"

The case arm treats $section as a shell glob, --get-regexp treats it
as a regex fragment and then the shell expansion uses it as a
literal.

The current set of callers give simple single-token like pretty,
remote, etc. to it so this is safe, but you may want to give a
comment to the function to help future generation, perhaps?

Other than that, looks quite straight-forward.

Thanks.
