[Biopython-dev] history on github - where are the tags?

By setting up a toy repository with tags done though git itself (I
assume), Bartek has convinced me that GitHub itself never shows the
tags in the history.  I think this is big drawback, and that we should
ask GitHub about this.

However, using the Mac GUI tool GitX, I was able to see the tags in
the history using the toy repository (they show up as nice yellow
blobs), but not using the current Biopython CVS to git conversion.
There appears to be something less than ideal about our CVS to git
conversion.  I believe this relates to how the tag commits appear in
the commit tree - and it looks like for Biopython they are all tiny
branches off the main trunk.  i.e. If you look at the main trunk
history (overall or for any one file) then tags commits are not in it.

This hunch appears to be supported by the git log output:

$ git clone git://github.com/biopython/biopython.git
$ cd biopython
$ git log --graph --all

In comparison, for Bartek's toy repository there is a single branch shown.
