Additional argument like "allow_abbrev_short" should be added to avoid those potential bugs due to abbreviations on short options cannot be handled by "allow_abbrev".

To reproduce and be well explanation, please check on my attached testing file.

The following is the excerpt:

1) contents in link:
   should be updated to long options (two dashes)

2) bugs may happen due to `allow_abbrev' cannot handle short options
   when recycling top-level arguments by using `add_subparsers'
