It has happened 680 times by a lot of different people. Tools that
export the repository are detecting these unnamed branches. The
branches are being reconstructed by correlating the commit comments.

There are 1,800 branches in the repository, that would imply that 1/3
of them had the magic tag removed manually.

The 680 number may be too high. The tool that is detecting these
doesn't necessarily get everything grouped back into a single branch
that belongs in that branch. So a single missing tag could cause the
tool to report a 100 extra branches if it is having trouble
correlating. I haven't checked everything manually so I don't know how
bad this problem is.
