Hi Jan,

[Cc'ing the list, in the unlikely event that anyone is using cvs/master:
 it has not been modified since Dec 2008]

Part of the problem is that the reference, "master", is ambiguous:

    sourceware$ git show-ref master
    22ff147254a15c977ca7eccc83567ba74587b8a3 refs/heads/cvs/master
    4959fdc11a310d335e57a69f597b64e1c155cefa refs/heads/hjl/x32/master
    f4a023ee8a2015d98fd3aeb50a5ccde2f201ec46 refs/heads/master

What you're getting is the first one: refs/heads/cvs/master:

    $ git show refs/heads/cvs/master:gdb/NEWS |sed 4q|tail -1
    *** Changes since GDB 6.8

What you want is the last one:

    $ git show refs/heads/master:gdb/NEWS |sed 4q|tail -1
    *** Changes since GDB 7.4

One way to fix this is to rename cvs/master and hjl/x32/master
so that there is no longer any ambiguity.

It's not impossible that this would be fixed by upgrading sourceware.org's
gitweb (currently at 1.7.3.4, it seems; while the latest is 1.7.9)
You can manually specify the full ref spec, too, but
you shouldn't have to resort to that:

  http://sourceware.org/git/?p=gdb.git;a=blob_plain;f=gdb/NEWS;hb=refs/heads/master

If you want to go for the rename, HJ can rename his branch
however he sees fit, but I'd have to rename the cvs/master one,
since it's also in the cvs-to-git source mirror, while HJ's branch
is present only in the public destination mirror.  I'll have to
rename cvs/master both in the private source, and in the public dest.

I propose to do both renames, like this:

    git branch -m cvs/master cvs/old-master
    git branch -m hjl/x32/master hjl/x32-master
