bash_completion: Fix -- flags detection
This fixes the help flags detection regex.
The previous regex expected flags to have a colon trailing the flag
name. This resulted in no flags ever being reported by the _flags func.
This colon does not appear to exist anymore in the --help menus.
This fix changes the regex to look for -- flags that contain
alpha numeric characters, =, -, or _s.
