Bash Version: 4.3
Patch Level: 30
Release Status: release

Description:
        Bash has incomplete documentation for builtins in `complete.def`. The 
[-abcdefgjksuv] options to specify
        types to complete are not documented. This is making writing 
completions some kind of black magic.
        
        All those correspondence can be found in complete.def. More 
specifically, compacts[].
        
        /* By the way is anyone going to assign those '\0's so we can do even 
more things? */

Repeat-By:
        help compgen, help complete, info bash, man bash.

Fix:
        Write approporiate doc for this. I only need a transcription of 
compacts[] so I can look it up without Luking it.
