That sort of information is in the pack files in .bzr/repository/; it's
nontrivial to parse these files to find the commit message of a
revision, without going through bzrlib.

Perhaps it would be a possibility to write a bzr plugin that dumps the
commit message to a file on disk on the server somewhere when it does a
push?
