Commit Limiting

Besides specifying a range of commits that should be listed using the special notations explained in the     description, additional commit limiting may be applied.

Using more options generally further limits the output (e.g. --since= limits to commits newer than , and using it with --grep= further limits to commits whose log message has a line that matches ), unless otherwise noted.

Note that these are applied before commit ordering and formatting options, such as --reverse.
