I think the command substitution and 'ls' are unnecessary, and

  shared=.git/sharedindex.*

would work as well.

If there is no shared index file with the above we would get:

shared=.git/sharedindex.*
$ echo $shared
.git/sharedindex.*

which seems bug prone to me.

It is not bug *PRONE*, but is already wrong, as the way this
variable is used is

        +		case "$shared" in
        +		*" "*)
        +			# we have more than one???
        +			false ;;
        +		*)
        +			test_modebits "$shared" >split_index_mode &&
        +			test_cmp index_mode split_index_mode ;;
        +		esac

i.e. we'd think there is a singleton ".git/shared/index.*" and we
can feed it to test_modebits.

So what you wrote originally is corrrect.
