Jonathan Nieder 6248e0fd1d launcher: simplify .repo search ceiling check 
In the .repo discovery loop

  while curdir != '/' and curdir != olddir:
    ... break if we found .repo ...
    olddir = curdir
    curdir = os.path.dirname(curdir)

the "while" condition is meant to avoid searching forever if we do not
find .repo before reaching the top-level directory of the filesystem.
For that purpose, the first half of the condition is redundant; once
we reach "/", the parent directory will be "/" again and the curdir !=
olddir check would suffice to terminate the search.  Simplify by
removing the redundant first half of the check.

Noticed by code inspection.  The first half of the check was retained
when introducing the second half in df14a70c ("Make path references OS
independent", 2011-01-09), in an excess of caution.

This also improves consistency a little: if I start with curdir =
'/home/me', then with the redundant check in place we search

	/home/me
	/home

before hitting / and giving up.  On Windows, if I start with
'c:/users/me', then we search

	c:/users/me
	c:/users
	c:/

before hitting a repetition and giving up.  Fortunately it is not
common for people to set up repo clients at the top level of
filesystems, but consistently following the latter behavior should
make debugging a little easier in case it comes up.

README.md

repo

Repo is a tool built on top of Git. Repo helps manage many Git repositories, does the uploads to revision control systems, and automates parts of the development workflow. Repo is not meant to replace Git, only to make it easier to work with Git. The repo command is an executable Python script that you can put anywhere in your path.

Contact

Please use the repo-discuss mailing list or issue tracker for questions.

You can file a new bug report under the "repo" component.

Please do not e-mail individual developers for support. They do not have the bandwidth for it, and often times questions have already been asked on repo-discuss or bugs posted to the issue tracker. So please search those sites first.

Install

Many distros include repo, so you might be able to install from there.

# Debian/Ubuntu.
$ sudo apt-get install repo

# Gentoo.
$ sudo emerge dev-vcs/repo

You can install it manually as well as it's a single script.

$ mkdir -p ~/.bin
$ PATH="${HOME}/.bin:${PATH}"
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/.bin/repo
$ chmod a+rx ~/.bin/repo
