merge: introduce tool.check parameter tool.check is a list of check options, and can be used in place of tool.checkchanged and tool.checkconflicts: Equivalences: tool.checkchanged = yes tool.checkconflicts = no tool.check = changed tool.checkchanged = no tool.checkconflicts = yes tool.check = conflicts tool.checkchanged = yes tool.checkconflicts = yes tool.check = changed, conflicts Add _toollist() wrapper for ui.configlist() to implement this consistently. checkchanged and checkconflicts are still supported, but check is preferred for implementing new check options.
