stupid: only check branch mappings for discovered files once
For whatever reason, we were processing the list of discovered files
for new branches every time we discovered a new file. This pulls the
process-discovered-files loop out of the discover-files loop, and
should reduce the running time from
O(num_paths_discovered * num_files_discovered) to
O(num_paths_discovered + num_files_discovered)
