[Q] Abbreviated history graph?

[Brian Foster <brian.foster@innova-card.com>]

Hello,

  A colleague and I recently wanted to examine the
 history in a broad sense without worrying too much
 about the individual commits.  What we (think we)
 wanted is a ‘gitk --all’ history graph showing only
 “named” historical points; i.e., tags and branch
 HEADs, perhaps with an indication of whether or not
 it's a “linear” change sequence that leads from one
 to another.  That is, hypothetically, if the history
 looks something like (where ‘A’ &tc has a name as
 per above, and ‘*’ does not):

     A--->*--->*--->C--->D--->*----->E
      \                   \         /
       \->*-->B            \->*--->*--->F

 What we wanted to see is something like:

     A------>C--->D--->E
      \       \       /
       \->B    \-----/--->F

 Is there some way of doing something similar to that
 (git v1.6.0.2)?  In addition to ‘gitk’, we also (rather
 quickly!) tried both ‘qgit’ and ‘giggle’, but without
 any apparent success.

cheers!
