Replace $repo with $repos/$reponame, c&p mistake
Add 'cd' command to enter a castle

The command will enter home/ if it exists, or else the repo root.

This requires the user to source a helper script (homeshick.{sh,csh})
that performs the 'cd' command within the context of the current shell.

If the main homeshick script is called with a 'cd' command, this just
displays the normal 'cd' help message, which indicates that homeshick
must be invoked via the helper script for the 'cd' command to work.
Move 'home/.homeshick' to 'bin/homeshick'

Also, move the helper scripts and update various paths as necessary.
Fix setup_homeshick() in the unit test setup
Add legacy symlink in old executable location
Add unit tests for cd command
Use source invocation method in all unit tests
Except when using expect, since we don't invoke a shell there
Fix #41. Allow numbers in github shorthand.
Kind of hard to create a unit test for this, since you can't suppress the http auth prompt.
Omitting for now.
Add more documentation for the cd command
Add links to command doc when it is mentioned
Add scenario for repos with no home/
Restructured README
version_compare() did not work correctly.
Was introduced in 26ba2573 by @goude,
none of the comparisons were adjusted despite
the return values being different from the replaced function.
Fix remote URL handling

* list() was missing a 'cd' into the repo directory.
* git-symbolic-ref's --short option is fairly recent and
  should be avoided for now.
Merge pull request #43 from jjlin/fix-remote-url

Fix remote URL handling.
Avoid --short option when calling symbolic-ref, it's fairly new.
Extend "Repos with no home" section
Fix branch name extraction

Instead of using basename, just remove the "refs/heads/" prefix.
With basename, branch names like "foo/bar" become just "bar".
