Otherwise Bash can cache a relative PATH and then get upset when it
changes directory and cannot find it any more.

This should help to avoid collisions with external commands and other
shell functions in the future and is closer to what we do in Ruby, where
commands are namespaced by being methods of the `Homebrew` module.
Remove the executable bit from the file to make it clear it is not
supposed to be executed directly. This should make the shebang line and
the early check also unnecessary.
Allow people to run this command (so we can ask people to test it)
without having to set `HOMEBREW_DEVELOPER`.

* only set HOMEBREW_UPDATE_BEFORE inside pull instead of fetch.
* fix HOMEBREW_UPDATE_BEFORE/AFTER variable settings. They should be set
to INITIAL_REVISION and CURRENT_REVISION correspondingly.
* avoid unnecessary duplicated shellout.
* remove unused variable.
* make sure exit after reset.
* more wide guardian range. We should trap reset_on_interrupt as soon as
we are about to change any files.
* check INITIAL_BRANCH against UPSTREAM_BRANCH
* use HOMEBREW_REPOSITORY instead of HOMEBREW_PREFIX
* better performance:
* update-bash: avoid shellout
* update-report: use strip_prefix and tr
* more robust:
* explicitly handle the case when repo is HOMEBREW_REPOSITORY to avoid
to handle the trailing backslash.
* handle both lower case and upper case when stripping non alpha and
digital characters.
