Added bash-compeltion from upsteam portage.

No changes were made--just deleted the 1.2 and left the 1.3 version,
since we don't need the 1.2 version.

BUG=chromium-os:13186
TEST=In	chroot:

1. sudo USE=bash-completion emerge git
2. eselect bashcomp enable git
3. exit
4. ./enter_chroot.sh
5. __git_ps1

...validate that this doens't cause an error.

+<longdescription>
+  Since v2.04, bash has allowed you to intelligently program and extend its
+  standard completion behavior to achieve complex command lines with just a
+  few keystrokes. Imagine typing ssh [Tab] and being able to complete on hosts
+  from your ~/.ssh/known_hosts files. Or typing man 3 str [Tab] and getting a
+  list of all string handling functions in the UNIX manual. mount system:
+  [Tab] would complete on all exported file-systems from the host called
+  system, while make [Tab] would complete on all targets in Makefile. This
+  project was conceived to produce programmable completion routines for the
+  most common Linux/UNIX commands, reducing the amount of typing sysadmins and
+  programmers need to do on a daily basis.
