[users at bb.net] How to get sufficient content in Changes for filtering

[Greg Bullock]

Sorry.  I forgot to append this snippet from the master.cfg file:

trunk_sf_codechanged = SingleBranchScheduler(name = "trunk_sf_codechanged",
                                      change_filter = filter.ChangeFilter(
                                                         repository = 
"svn://kraken" if _hypersensitive_SVNPoller else 
"svn://kraken/trunk/sf_code",
                                                         branch = None,
                                                         # 
codebase_re=re.compile(gpsii_src_dirs_pat, re.I),
                                                         #  -- Filtering 
with codebase_re didn't work because typical Changes
                                                         #     has empty 
codebase (and other) fields, e.g.,
                                                         #
