Adding glob-like matching in addition to the prefix-based matching introduced previously (patch 1). 2. Adding the ability to recover the PMU names when printing the events separately with the --no-merge option (patch 2). 3. Restoring auto-merge for events created by prefix or glob-like match (patch 3). Note that this still keeps the behavior that disables auto-merging of legacy symbolic events (e.g. cycles).
