Two difference:
--compgen
accept two arguments only, one for sript path, one for command line buffer.argc --compgen ./mycmd1 download
=>argc --compgen ./mycmd1 'download '
The space in the end is very import. Having space or not having space will generate completely different results. After this PR merged, argc can recognize this difference.
