I know you probably want confirmation from Mikko, but I'll offer my
understanding.  There were two statements added in bcd57cb9:

1. -f may need to be given twice to delete nested worktrees and
embedded repositories.  This is still true.

2. Deletion of submodule repositories under .git/modules is conditional
on -f being given twice.  AFAICT, this was wrong even back then: "git
clean" has never deleted such repositories under any conditions.

My patch is only removing #2.
