[PATCH 2/2] bash: Use dynamic binding for subcommand completion functions

[Teemu Matilainen <teemu.matilainen@iki.fi>]

Call git subcommand completion functions dynamically using the same
logic as with external commands.  I.e. call '_git_<subcommand>' if it
exists.

The only exceptions now are:
  - stage -> _git_add
  - whatchanged -> _git_log

This only changes how the functions are called.  The functionality remains
exactly the same.
