The actual phrasing of the message is fine per se. The real problem is
that this is not actually an error, it is a missing feature by design.
Thus the fact that an error message is issued is the error.
I am not sure what I think the right solution is here as there are too
many variables: bzr, bzr-svn, svn, bzr-git, git, Bazaar Explorer are
In the Bazaar Explorer context it needs to be made clear when a
Subversion or Git repository (also Mercurial and Darcs?, though the
latter is increasingly less likely to be an issue I suspect) is
involved. Although bzr-svn and bzr-git try and completely decouple
Bazaar usage and presentation from interaction with a remote repository,
the separation is not 100% and there needs to be a flag (*). With the
flag in place then messages about Git coming from Bazaar interaction are
less likely to be shocking.
I am more worried about Subversion in this context than Git as I think
bzr-git is a useful addition to the armoury but bzr-svn is critical to
the future of Bazaar.
(*) This is critically important when NFS filestores are involved on
Linux for reasons deep in the mire of TDB !
