Create an ant task to display commits since last patch of a given module
Patches of modules are distributed as a zip containing the entire module. This means that someone can release a patch that accidentally includes someone else's work, if that someone had been committing their changes to the release branch of the same module (possibly working on a different patch). Before issuing a patch, it is handy to look at the version control log and see if there are any suspect commits that you might be inadvertently including.
The new ant task would execute 'svn log' for the range of revisions between that of the last patch issuance and HEAD.
