Now the parameter completion is only available for subcommands
delivered with git. Providers of external subcommands do not have
a way to supply bash completion for their commands (other than
instructing users to hack their git-completion.bash file).
This makes it possible to have completion also for external git
subcommands. It can be provided by specifying a function (or a
command in PATH) '_git_<subcommand>' that sets the environment
variable COMPREPLY.
All dashes (-) in the subcommand name are replaced with underscores
(_). E.g. completion for command 'git foo-bar' can be provided by
'_git_foo_bar'.
