; is dangerous character, so just use newlines to separate commands.

It will make tracking bug easier. Also explain reason of debug info.

Sometimes .git disappears, and bt5 and product/ERP5/bootstrap changes
permission. Thanks to listing directory contents it will allow to know if
state of directory is correct before git pull.

; are used in order to allow to progress in case of issue, as ls shall not
generate part installation error.

Git v1.7.8.4 Release Notes
==========================

Fixes since v1.7.8.3
--------------------

 * The code to look up attributes for paths reused entries from a wrong
   directory when two paths in question are in adjacent directories and
   the name of the one directory is a prefix of the other.

 * A wildcard that matches deeper hierarchy given to the "diff-index" command,
   e.g. "git diff-index HEAD -- '*.txt'", incorrectly reported additions of
   matching files even when there is no change.

 * When producing a "thin pack" (primarily used in bundles and smart
   HTTP transfers) out of a fully packed repository, we unnecessarily
   avoided sending recent objects as a delta against objects we know
   the other side has.

 * "git send-email" did not properly treat sendemail.multiedit as a
   boolean (e.g. setting it to "false" did not turn it off).

Also contains minor fixes and documentation updates.
