revision.c: add a new option 'merges' with
possible values of 'only', 'show' and 'hide'.
The option is used when showing the list of commits.
The value 'only' lists only merges. The value 'show'
is the default behavior which shows the commits as well
as merges and the value 'hide' makes it just list commit
items.
