    Since Gitter has the ability to perform message updates (it lets users edit their most recent message) the Matrix-Gitter bridge has to handle this. Currently it does it by performing a diff between the old and new content, stripping a common prefix and suffix and then presenting the resulting change on the Matrix side in a (somewhat) helpful way. I've made mention of this spec bug in the code there, so if a better means arrives in Matrix to represent this it can be updated.
