45 Parameterize StatusCollector to produce copy only when needed. And HgDataFile.metadata perhaps should be moved to cacheable place? 45 Parameterize StatusCollector to produce copy only when needed. And HgDataFile.metadata perhaps should be moved to cacheable place?

49 Status operation from GUI - guess, usually on a file/subfolder, hence API should allow for starting path (unlike cmdline, seems useless to implement include/exclide patterns - GUI users hardly enter them, ever) 47 Status operation from GUI - guess, usually on a file/subfolder, hence API should allow for starting path (unlike cmdline, seems useless to implement include/exclide patterns - GUI users hardly enter them, ever)
50 -> recently introduced FileWalker may perhaps help solving this (if starts walking from selected folder) for status op against WorkingDir? 48 -> recently introduced FileWalker may perhaps help solving this (if starts walking from selected folder) for status op against WorkingDir?
