Thanks for catching.

I've squashed the patches and rewrote the commit message.

In b3256eb (standardize and improve lookup rules for external local
repos), enter_repo() was modified to use a different precedence ordering
of suffixes for DWIM of the repository path, and to ensure that the
repository path is actually valid instead of just testing for existence.
However, the documentation was not modified to reflect these changes.
As such, fix the documentation to match the code.
