[PATCH] Replace code with just a simple list comprehension

[Vincent Legoll <vincent legoll gmail com>]

I think this code is more complicated that the
simple and natural equivalent list comprehension

Kai, do you want me to commit this, will it become
obsolete with your historyentry.py work, or will you
integrate it in your patch series ? I don't want to
interfere...
