What is the expected output? What do you see instead?

  Expected output:

    ----------------------------
    Project: dir/name
    Mount path: dir/name

    ...

  Actual output:

    $ repo info

I've found the problem in the manifest file: the default element is lacking a 
revision attribute. I was able to workaround the bug in git-repo by adding the 
missing attribute to my manifest file:

-  <default remote="server"/>  
+  <default revision="master" remote="server" />

But in the end, there's either a bug in git-repo code or in documentation,
since the associated DTD doesn't seems to require revision attribute:

    <!ELEMENT default (EMPTY)>
    <!ATTLIST default remote      IDREF #IMPLIED>
    <!ATTLIST default revision    CDATA #IMPLIED>
    <!ATTLIST default dest-branch CDATA #IMPLIED>
    <!ATTLIST default sync-j      CDATA #IMPLIED>
    <!ATTLIST default sync-c      CDATA #IMPLIED>
    <!ATTLIST default sync-s      CDATA #IMPLIED>
