Certainly without at least commit (and diff would be nice) I can't go
any further with jgit on VMS today.  We will have to use jsvn for the
interim (our repositories are currently in svn anyway, and jsvn is
reasonably full-featured and functional on VMS).  But it's nice to have
a migration path in the offing.

Should I return to jgit, I could look into this (though I am not a Java
programmer).

Glad to hear it.  I have taken note in case I revive this effort later.

Before I sign off entirely, I'd like to mention also that I tried using
the ssh protocol without success:
